Praise and thanks to Allah for the givings He granted without Him being obligated to do so. May Allah raise the rank of the Messenger of Allah, Muhammad and protect his Ummah from that which he fears for it. May the mercy of Allah be upon the Al and Sahb of the Prophet. [The Al of Prophet Muhammad, includes his wives, Muslim kin, and the pious Muslims of his Ummah. The Sahb or Sahabah of Prophet Muhammad are the people who met with him, believed in him, and died Muslim.]
Know that the reason for writing this treatise is that many people thought that attributing the hadd (limit) and the jismiyyah (bodily characteristics) to Allah, and prohibiting the tawassul (asking Allah for things by some good people or deeds) by the anbiya' (prophets) and awliya' (righteous Muslims) after their death, and the tabarruk (seeking the blessing of Allah) by visiting their graves are the beliefs and actions of the Salaf.
Since the situation is as such, the necessity called for showing that the truth of the matter is different from what is thought. In other words, the Salaf had the belief that Allah is clear of the hadd, i.e., that Allah never had a hadd. Moreover, Allah does not have a hadd according to His knowledge or to the knowledge of the creation. Performing the tawassul by the anbiya' and awliya' after their death and the tabarruk by visiting their graves hoping for the fulfillment of their du^a' (supplication, asking Allah) at their graves is the condition in which the Salaf were. We wanted to show that Imam Ahmad Ibn Hanbal was different from what Ibn Taymiyah innovated. We saw that it is obligatory to expose this imposture by showing that the Ijma^ permits the tawassul by the anbiya' and awliya' after their death, that the going (of the Muslims) to the graves of those people with the purpose of tabarruk is not shirk (associating partners with Allah), and that touching the grave for tabarruk is permitted, has no shirk in it, and is not haram (prohibited, sinful). This treatise is full of Islamic proofs. The reader, by the will of Allah, will see them in detail.
