Farwa b. Naufal quoted his father as saying that he had asked God's messenger to teach him something to say when he went to bed, and was told to recite, “Say, O infidels”, for it is a declaration of freedom from polytheism.
The Prophet, on hearing a man reciting “Say, He is God, One” remarked, “It is certain.” I asked him what was certain, and he replied that it was paradise.
While I was travelling with God's messenger between *al-Juhfa and al-Abwa’ a wind and intense darkness enveloped us, whereupon God’s messenger began to seek refuge in God, reciting “I seek refuge in the Lord of the dawn” and “I seek refuge in the Lord of men.”(Qur’ān, 113 &114) He then said, “Use them, ‘Uqba, when seeking refuge in God, for no one can use anything to compare with them for the purpose.”
*Al Juhfa- a village about 82 miles from Mecca. Al Abwa’- a village between twenty and thirty miles nearer Medina than al-Juhfa.
He reported the Prophet as saying, “If anyone who is about to sleep on his bed lies on his right side, then recites ‘Say, He is God, One’ a hundred times, the Lord will say to him on the day of resurrection, ‘My servant, enter paradise to your right’.”
Tirmidhī transmitted it, saying this is a hasan gharīb tradition.
