Sahih Muslim Book 32, Hadith Number 6372.
Chapter : The merit of one who resigns himself to the will of God calmly at the time of the death of one’s son.
Abu Huraira reported that a woman came to Allah’s Apostle (may peace be upon him) with her child and said: Allah’s Messenger, he is ailing, and I am afraid (that he may die), as I have already buried three. Thereupon he said: It (their sad demise) would be a protection against Hell-Fire for you. Zuhair has not mentioned the kunya of Abu Ghiyath; he has mentioned his name.
