WE RELATE IN the book of Ibn as-Sunnī from Ibn ‘Abbās 
, who reported that the Messenger of Allah 
said: “Death is a shock, so if any one of you hears about the death of his brother let him say: We are from Allah and to Him do we return, and we shall surely be brought back to our Lord. O Allah, record him in Your sight among the virtuous, make his book [of actions] to be in ‘Illiyyūn [the highest heaven], and give him a successor in his family among those who remain. Do not deprive us of his reward, and do not put us to trial after him.” [1].

Innā li-llāhi wa innā ilayhi rāji‘ūn, wa innā ilā Rabbinā la-munqalibūn, Allāhumma-ktubhu ‘indaka fi-l-muḥsinīn, wa-j‘al kitābahu fī ‘Illiyyīn, wa-khlufhu fī ahlihi fi-l-ghābirīn, wa lā taḥrimnā ajrahu wa lā taftinnā ba‘dah.

Ibn Ḥajar states that this is a gharīb hadith, reported by Ibn as-Sunnī; its chain contains Qays ibn Rabī‘, who is very truthful (ṣadūq) but who mixed up his narrations towards the end of his life and did not differentiate, so that anything which he is alone in reporting is weak. Al-Futūḥāt (4/124).
