Re: Jadu, Tona, Nazar, Bandish…
Any Muslim can perform Istikhara on his/her own.
Here’s the method: How to pray istikhaarah
It has well known that we should recite the last thee surahs of the Quran to protect ourselves from the evil eye and other harm. In addition, reciting the last two verses of Surah Baqarah before going to bed are also recommended as well as ayatul-Kursi.
Here are the details: Prescribed means of warding off sihr (witchcraft) before it happens
Cure:
In the event that you are afflicted by the evil eye, you should use the treatments recommended in sharee’ah, which are:
1 – Reciting ruqyah. The Prophet (peace and blessings of Allaah be upon him) said, “There is no ruqyah except in the case of the evil eye or fever.” al-Tirmidhi, 2057; Abu Dawood, 3884. Jibreel used to do ruqyah for the Prophet (peace and blessings of Allaah be upon him) and say, “ Bismillaahi arqeeka min kulli shay’in yu’dheeka, min sharri kulli nafsin aw ‘aynin haasid Allaahu yashfeek, bismillaahi arqeek (In the name of Allaah I perform ruqyah for you, from everything that is harming you, from the evil of every soul or envious eye may Allaah heal you, in the name of Allaah I perform ruqyah for you).”
2 – Asking the person who has put the evil eye on another to wash, as the Prophet (peace and blessings of Allaah be upon him) commanded ‘Aamir ibn Rabee’ah to do in the hadeeth quoted above. Then the water should be poured over the one who has been afflicted.
With regard to taking his waste, such as his urine and stools, there is no basis for doing so; the same applies to taking any of his belongings. Rather what is narrated is that which is mentioned above, washing his limbs and washing inside his garment, or likewise washing inside his headgear and garments. And Allaah knows best.
There is nothing wrong with taking precautions against the evil eye before it happens, and this does not contradict the idea of tawakkul (putting one’s trust in Allaah). In fact this is tawakkul, because tawakkul means putting one’s trust in Allaah whilst also implementing the means that have been permitted or enjoined. The Prophet (peace and blessings of Allaah be upon him) used to seek refuge for al-Hasan and al-Husayn and say: U’eedhukuma bi kalimaat Allaah al-taammati min kulli shaytaanin wa haammah wa min kulli ‘aynin laammah (I seek refuge for you both in the perfect words of Allaah, from every devil and every poisonous reptile, and from every evil eye).’” Al-Tirmidhi, 2060; Abu Dawood, 4737. And he would say, “Thus Ibraaheem used to seek refuge with Allaah for Ishaaq and Ismaa’eel, peace be upon them both.” Narrated by al-Bukhaari, 3371.
