He then said: I heard the Apostle of Allah (peace_be_upon_him) as saying: If anyone's intercession intervenes as an obstacle to one of the punishments prescribed by Allah, he has opposed Allah; if anyone disputes knowingly about something which is false, he remains in the displeasure of Allah till he desists, and if anyone makes an untruthful accusation against a Muslim, he will be made by Allah to dwell in the corrupt fluid flowing from the inhabitants of Hell till he retracts his statement.

Hadith Qudsi 5:
On the authority of Abu Hurayrah (may Allah be pleased with him), who said that the Messenger of Allah (PBUH) said: Allah (glorified and exalted be He) said:
I am so self-sufficient that I am in no need of having an associate. Thus he who does an action for someone else's sake as well as Mine will have that action renounced by Me to him whom he associated with Me.

Hadith Qudsi 6:
On the authority of Abu Hurayrah (may Allah be pleased with him), who said: I heard the Messenger of Allah (PBUH) say:
The first of people against whom judgment will be pronounced on the Day of Resurrection will be a man who died a martyr. He will be brought and Allah will make known to him His favours and he will recognize them. The Almighty] will say: And what did you do about them? He will say: I fought for you until I died a martyr. He will say: You have lied - you did but fight that it might be said [of you]: He is courageous. And so it was said. Then he will be ordered to be dragged along on his face until he is cast into Hell-fire. [Another] will be a man who has studied [religious] knowledge and has taught it and who used to recite the Quran. He will be brought and Allah will make known to his His favours and he will recognize them. [The Almighty] will say: And what did you do about them? He will say: I studied [religious] knowledge and I taught it and I recited the Quran for Your sake. He will say: You have lied - you did but study [religious] knowledge that it might be said [of you]: He is learned. And you recited the Quran that it might be said [of you]: He is a reciter. And so it was said. Then he will be ordered to be dragged along on his face until he is cast into Hell-fire. [Another] will be a man whom Allah had made rich and to whom He had given all kinds of wealth. He will be brought and Allah will make known to his His favours and he will recognize them. [The Almighty] will say: And what did you do about them? He will say: I left no path [untrodden] in which You like money to be spent without spending in it for Your sake. He will say: You have lied - you did but do so that it might be said [of you]: He is open-handed. And so it was said. Then he will be ordered to be dragged along on his face until he is cast into Hell-fire.
It was related by Muslim (also by at-Tirmidhi and an-Nasa'i).
On the authority of Abu Dharr al-Ghifari (may Allah be pleased with him) from the Prophet (PBUH) is that among the sayings he relates from his Lord (may He be glorified) is that He said:
O My servants, I have forbidden oppression for Myself and have made it forbidden amongst you, so do not oppress one another. O My servants, all of you are astray except for those I have guided, so seek guidance of Me and I shall guide you, O My servants, all of you are hungry except for those I have fed, so seek food of Me and I shall feed you. O My servants, all of you are naked except for those I have clothed, so seek clothing of Me and I shall clothe you. O My servants, you sin by night and by day, and I forgive all sins, so seek forgiveness of Me and I shall forgive you. O My servants, you will not attain harming Me so as to harm Me, and will not attain benefitting Me so as to benefit Me. O My servants, were the first of you and the last of you, the human of you and the jinn of you to be as pious as the most pious heart of any one man of you, that would not increase My kingdom in anything. O My servants, were the first of you and the last of you, the human of you and the jinn of you to be as wicked as the most wicked heart of any one man of you, that would not decrease My kingdom in anything. O My servants, were the first of you and the last of you, the human of you and the jinn of you to rise up in one place and make a request of Me, and were I to give everyone what he requested, that would not decrease what I have, any more that a needle decreases the sea if put into it. O My servants, it is but your deeds that I reckon up for you and then recompense you for, so let him finds good praise Allah and let him who finds other that blame no one but himself.
