´Mus'ab bin Sa'd narrated that his father said:` "The Messenger of Allah said: 'The best of you is the one who learns the Qur'an and teaches it.' " 'Then he (Mus'ab) took me (the narrator) by the hand and made me sit here, and I started to teach Qur'an.'"

´It was narrated that Ibn 'Umar said:` "The Messenger of Allah said: 'Allah does not accept any prayer without purification, and He does not accept any charity from ghulul.'"

´It was narrated from Mus’ab bin Sa’d that his father said:` “For the Fajr prayer on Fridays, the Messenger of Allah (ﷺ) used to recite ‘Alif-Lam-Mim. The revelation...’ [32:1] and ‘Has there not been over man...’” [76:1]

´It was narrated that Mus’ab bin Sa’d said:` “I bowed (in prayer) beside my father, and I put my hands between my knees. He struck my hand and said: ‘We used to do that, then we were commanded to put them on the knees.’”

´It was narrated that Sa'd said:` "I took an oath by Lat and 'Uzza. The Messenger of Allah (ﷺ) said : 'Say: "La ilaha illallah wahdahu la sharika lahu" (None has the right to be worshipped but Allah alone, with no partner or associate)," then spit toward your left three times, and seek refuge with Allah, and do not do that again."'

´It was narrated from Mus’ab bin Sa’d that his father, Sa’d bin Abu Waqqas, said:` “I said: ‘O Messenger of Allah, which people are most severely tested?’ He said: ‘The Prophets, then the next best and the next best. A person is tested according to his religious commitment. If he is steadfast in his religious commitment, he will be tested more severely, and if he is frail in his religious commitment, his test will be according to his commitment. Trials will continue to afflict a person until they leave him walking on the earth with no sin on him.’”
