Narrated Abu Huraira reported God’s Messenger as saying:
When one of you recites, "By the fig and the olive”1 and comes to "Is not God the best of judges?”2 he should say, "Certainly, and I am one of those who testify to that.” When one recites, "I swear by the day of resurrection”3 and comes to "Is not that One able to raise the dead to life?’4 he should say, "Certainly.” And when one recites, "By those that are sent”5 and comes to "Then in what message after that will they believe?”6 he should say, "We believe in God.”
Narrated Jabir said that God’s Messenger came out to his companions and recited to them Sura ar-Rahman1 from beginning to end, but they remained silent. He then said:
I have recited it to the jinn on the night they came to me, 2 and they responded better than you. As often as I came to the words, "Then which of the favours of your Lord do you deny?” they replied, "We deny none of Thy favours, O our Lord. To Thee be the praise.”
1. Al-Qur’an; 55.
2. When the Prophet was returning to Mecca after being rejected by the people of at-Ta’if.
Tirmidhi transmitted it and said this is a gharib tradition.
‘Abdallah b. Abu Aufa told of a man who came to the Prophet and said, “I am unable to learn any of the Qur’an, so teach me something which will suffice me.” He told him to say, “Glory be to God; Praise be to God; There is no god but God; God is most great; There is no might and no power except in God.” He said, “Messenger of God, this is for God; but what is there for me?” He told him to say, “O God, have mercy on me, heal me, guide me, and provide for me.” He said that the man clenched his hands, whereupon God’s Messenger said, “This man has filled his hands with good.”
Abu Dawud transmitted it, and Nasa’i’s transmission finished with “except in God.”
