Whether the isthigasa is permitted in islam? Explain with islamic kithab

Istighātha in Arabic means to seek help and aide; and when used in the Islamic sciences there is no difference in meaning.

There are a number of close synonyms to istighātha such as istikhāra [seeking a decision] and isti'āna [seeking help]. However, as noted by the scholars of language, Istighātha is used when one is under a state of duress.

Scholar of Islam gave four rulings for istighātha:

1. Permissibility- It is permissible to help from others and, at times it can be recommended. This applies to asking one's brothers to pray for him asking Allah to bless him and raise his status; and, if there is a need, its is permissible to seek one's aide physically. However, there is an important etiquette noted by the Ulema, one should not do so with a humble voice and awe mimicking the way one would ask Allah the Most High.
2. Recommended- This is related to asking Allah the Most High by His blessed names and attributes.
3. Obligation- If one was facing certain death or about to perish, then it is an obligation upon him to beseech the aide and assistance of one who could help him.
4. Forbidden- If one were to ask from those who have no power or ability to help him believing at the time he sought such aide that the power came from the one questioned [the prophet, or prophets, saint or others] and not Allah then this is forbidden by the consensus of jurists.

Istighātha (Supplicating and Calling) on Allah:

It is recommended to do so as was noted in the Qur'anic verse, “When you sought the help of your Lord and He answered you.” Surah al-Anfāl. Anas bin Malik related that the Prophet (pbuh) said, “Oh the Living The Sustainer which your mercy I beseech support.”

Istighātha (calling on and suplicating to) Other than Allah

As for istighath with the dead or anyone else for that matter, thinking that they can come out of their grave and bring assistance, then there is no question about the forbidden nature of this action. May Allah guide us.

Tawassul with the Prophet (pbuh)

This relates to three scenarios:

1. During his life time- Scholars agreed that it was permissible to do so based on a number of Qu'ranic verses and prophetic traditions.
2. After his death [see below]
3. To make tawassul to Allah by mentioning the Prophet seeking to draw nearer to Allah (pbuh). “Oh Allah I see to draw nearer to you with [our faith in] our Prophet Muhammad (pbuh).” [see below]
