It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "If, while praying, you become doubtful whether you have prayed three rak'ahs or four, then if your predominant thought is that you have prayed three rak'ahs, stand up and pray one rak'ah, then say salam and perform two prostrations of forgetfulness (sahw), and recite tashahhud and then say salam. But if your predominant thought is that you have prayed four rak'ahs, then recite tashahhud and, before saying salam, perform two prostrations of forgetfulness while sitting, then recite tashahhud again and say salam."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "If three children of a Muslim husband and wife die before reaching puberty, they will become a strong fortress for them against Hell." Someone asked: O Messenger of Allah! What if someone has lost two children? The Prophet (peace and blessings be upon him) said: "The same ruling applies." Sayyiduna Abu Darda (may Allah be pleased with him) said: O Messenger of Allah (peace and blessings be upon him)! I have sent forth two children? He replied: "The same ruling applies." Sayyiduna Ubayy ibn Ka'b (may Allah be pleased with him) — who is famous as the leader of the reciters — said: Only one of my children has died? The Prophet (peace and blessings be upon him) said: "The same ruling applies to him, but this matter is related to the initial moments of grief (as to who is patient at that time and who is not, because later on everyone becomes patient)."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: None of you should give Satan any power over himself, not even to the extent of a portion, and he should not think that it is necessary for him to return only from the right side. I have seen the Prophet (peace and blessings of Allah be upon him) that his return was often from the left side.

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "It is a very bad thing that any one of you says, 'I forgot such-and-such verse,' rather he should say, 'It was made to be forgotten by me.'"
