Calling upon Allah, remembering Him, praising Him and sending blessings on His Messenger.
'Ali (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "The miser is the one in whose presence I am mentioned but he does not supplicate for me."
Abul-Fadl Al-`Abbas bin `Abdul-Muttalib (ra) reported: I asked the Messenger of Allah (ﷺ) to teach me a supplication. He (ﷺ) said, "Beg Allah for safety (from all evils in this world and in the Hereafter)." I waited for some days and then I went to him again and asked him: "O Messenger of Allah Teach me to supplicate something from Allah." He said to me, "O Al-`Abbas, the uncle of Messenger of Allah! Beseech Allah to give you safety (Al-`afiyah ) in this life and in the Hereafter."
