Sunan Ibn Majah Book 34, Hadith 66
“Whoever unexpectedly comes across a person suffering a calamity, and says: Al-hamdu Lillahil-ladhi ‘afani mim-mabtalaka bihi, wa faddalani ‘ala kathirin mimman khalaqa tafdila (Praise is to Allah Who has kept me safe from that which has afflicted you and preferred me over many of those whom He has created), will be kept safe from that calamity, no matter what it is.’”
“If the Messenger of Allah (ﷺ) saw a cloud that looked as if it was bringing rain, the color of his face would change, and he would go in and out and walk to and fro. Then, if it rained, he would feel relieved.” ‘Aishah mentioned to him what she had seen him do, and he said: “How do you know? Perhaps it would be as the people of Hud said: ‘Then, when they saw it as a dense cloud coming towards their valleys, they said: “This is a cloud bringing us rain!” Nay, but it is that (torment) which you were asking to be hastened.”
“A good dream from a righteous man is one of the forty-six parts of prophecy.”
