THE LEGACY OF ISLAM & PROPHET: THE AHLE BAYT!
Here's some proof from the Quran.
1)And are not the Ahl al-Bayt "those whom Alláhs has blessed" about whom the Holy Qur'án says:
"Guide us in the straight path, the path of those whom Thou hast favoured; Not the (path) of those who earn Thine anger nor of those who go astray." (Holy Qur'án 1:6-7)
2)And was the "Verse of Imprecation" revealed with reference to any other person except the Prophet's Ahle Bayt?
"And whoever disputes with thee concerning him after the inspired knowledge which has been given to thee, tell him 'Come, let us call our sons and your sons; our women and your women; our ourselves and yourselves; then let us pray and invoke Alláh's curse upon those who lie." (Holy Qur'án 3:61)
3)Are they[Ahle Bayt] not the "Rope of Alláh" about whom he has said: “Hold fast to the Rope of Alláh, all of you together, and do not diverge” Holy Qur'án 3:103
4)Are not the Ahl al-Bayt "the true believers" about whom Alláh says:
"Whoever opposes the Prophet after the guidance has been manifest unto him and follows any path other than the path of the true believers, We will turn him towards that unto which he himself has turned, and We will expose him to Hell and a bad journey it will be." (Holy Qur'án 4:115)
5)The Ahl al-Bayt alone are those who are "supreme in authority" as referred to in the verse: "O you who believe, obey Alláh and obey His Messenger and those who are supreme in authority amongst you."
(Holy Qur'án 4:59)
6)And in another verse he says: "They are those whom Alláh has blessed among the Prophets and the verifiers, the martyrs and the righteous." (Holy Quran 4:69)
7)Is it not a fact that Alláh has given the Ahl al-Bayt the leadership of the people generally and that after the Holy Prophet He has placed the leadership exclusively amongst them?
Read the verse: "Verily your leader is only Alláh, and His Messenger, and those who believe; who establish worship and pay the poor due while they are bowing down in prayer." (Holy Qur'án 5:55)
8)Are not the Ahl al-Bayt the "path" about whom Alláh says: "Lo, this is My straight path, so follow it and do not follow other ways else you will diverge from His way." (Holy (Qur'án 6:153)
9)They [Ahle Bayt] are the people to whom the khums [the charity of one-fifth] is due. Unless and until a person sets aside the khums he cannot be deemed to have paid his dues. Accordingly, the Qur'án says:
"And know that whatever you take of the spoils, lo! a fith thereof is for Alláh and for the Messenger and for his kinsmen." (Holy Qur'án 8:41)
10)Are they [Ahle Bayt] not the truthful about whom He says:re they not the truthful about whom He says: "Be careful of your duty to Alláh and be with the Truthful." Holy Qur'án 9:119
11)Are not the Ahl al-Bayt the "guides" about whom Alláh says:
"Lo! thou art a warner and for every people there is a guide." (Holy Qur'án 13:7)
12)Is it not a fact that Alláh has made His promise of pardon to those who believe and do good conditional upon their being guided by the Ahl al-Bayt?
The Qur'án says:
"And lo! I am the Most Forgiving towards him who repents and believes and does good and then follows the guidance." (Holy Qur'án 20:82)
13)Are not the Ahl al-Bayt those who remember regarding whom Alláh says:
"Ask those who remember if you do not know." (Holy Qur'án 21:7)
14)Also, it is about them and their enemies that Alláh says:
"These [the believers and disbelievers] are two opponents who quarrel about their Lord. Therefore, as for those who disbelieve, clothes of fire will be cut out for them [and] a boiling liquid will be poured down upon their heads." (Holy Qur'án 22:19)
15)Concerning them and their enemies the following verses were revealed:
"Is he who is a believer like he who leads an evil life? They are not alike. But as for those who believe and do good deeds, for them are the Gardens of the Abode, a reward for what they used to do. While for those who do evil, their Abode is the Fire. Whenever they try to go out therefrom, they are brought back, and it is said to them: Taste the torment of the Fire which you used to deny." (Holy Qur'án 32:18-20)
16)Can you say that there are such clear verses in the Holy Qur'án concerning anyone else as there are about the Ahl al-Bayt? Does the Holy Qur'án contain an unequivocal declaration of the removal of all contamination from anyone except the Ahl al-Bayt? Has any verse like the "Verse of Purity" been revealed concerning any other person?
"It is Alláh's will to remove all blemish from you, O Ahl al-Bayt, and purify you with a perfect purification." (Holy Qur'án 33:33)
17)It is upon the family of Muhammad that Alláh commands us to invoke blessings, saying: "Lo! Alláh and His angels shower blessings on the Prophet. O you who believe! Bless him and salute him with a worthy salutation" (Holy Qur'án 33:56)
18)The Muslims asked the Holy Prophet, "How are we to salute you?" and he replied,
"Say, 'O Alláh! Bless Muhammad and the Family of Muhammad'"
Therefore, it is proved by this tradition that the salutation is not complete unless and until the Family of Muhammad is also saluted along with the Prophet. This is the reason that the learned men and research scholars have included the above-mentioned verse among those verses of the Holy Qur'án which praise the Ahl al-Bayt. Hence, they are the chosen servants of Alláh and they are the forerunners who hasten towards righteousness by the command of Alláh, and they are the inheritors of the Book of Alláh concerning whom the Almighty says:
"Then We gave the Scripture as an inheritance unto those of Our servants whom We selected. But of them are some whom wrong themselves and some who take the middle path and some who surpass all others in their good deeds by Alláh's command. that is the great favor." (Holy Qur'án 35:32)
19)Is there any verse which commands us to love anyone else as we are commanded to love the Ahl al-Bayt?
"Say, I ask no reward from you for it except the love of my kinsfolk. And whosoever doeth a good deed we add unto it a greater good for him. Lo, Alláh is Forgiving, Responsive." (Holy Qur'án 42:23)
The above are only a few re: the proof that Allah's nominated servants from Abraham down to Muhammed share the same lineage and this lineage continued down with the Ahle Muhammed and the Ahle Bayt Imams.
