Sayyiduna Ibn Abbas (may Allah be pleased with them both) reports that the Messenger of Allah (peace and blessings be upon him) said: "Whoever makes forty mornings purely for Allah, streams of wisdom will flow from his heart onto his tongue." It is as if the Prophet (peace be upon him) meant the person who attends the congregational prayer of Isha and Fajr for forty days. "And whoever attains these two prayers with the first takbir for forty days, for him there are two salvations: for a man, there are two salvations, one salvation from the Fire and one salvation from hypocrisy."
