Sa‘d b. Abu Waqqas said that a nomadic Arab come to God's messenger and asked him to teach him some words to say. He told him to say, “There is no god but God alone who has no partner; God is very great; Abundant praise is due to God; Glory be to God, the Lord of the universe; There is no might and no power except in God, the Mighty, the Wise.” On his remarking that these were for his Lord but he wanted to know what he should say for himself, he told him to say, “O God, forgive me, show mercy to me, guide me, provide for me, and grant me security.” The transmitter was doubtful about “grant me security.”
Busaira, who was one of the women emigrants, told of God’s messenger saying to them, “Apply yourselves to glorifying God, saying there is no god but He, and declaring His holiness; and count them on your fingers, for they will be questioned and asked to speak; and do not be negligent and so be deprived of mercy.”
Anas said that, on coming upon a tree whose leaves were withered, God's messenger struck it with his staff, and the leaves were scattered. He then said that “Praise be to God; Glory be to God; There is no god but God; and God is most great” cause a man's sins to fall away just as the leaves of that tree were falling.
Tirmidhi transmitted it, saying this is a gharib tradition.
Ibn Mas'ud reported God's messenger as saying he met Abraham on the night he was taken up to heaven, and he said, “Convey my greeting to your people, Muhammad, and tell them that paradise has good soil and sweet water, that it consists of level, treeless plains, and that its plants are ‘Glory be to God’; ‘Praise be to God’; ‘There is no god but God’; and ‘God is most great’.”
Tirmidhi transmitted it, saying this is a hasan tradition whose isnad is gharib.
