Jami` at-Tirmidhi Book 48, Hadith 193
that he sought permission from the Prophet (ﷺ) concerning `Umrah, so he said: “O my little brother, include us in your supplication and do not forget us.”
That the Prophet (ﷺ) sent an expedition in the direction of Najd. They gained many spoils of war and returned quickly. A man among those who did not go out said: “We have not seen an expedition quicker in return or greater in spoils than this expedition.” So the Messenger of Allah (ﷺ) said: “Should I not direct you to a group greater in spoils and quicker in return? A group who attended Salat As-Subh, then sat remembering Allah until the sun rose, for these are quicker in return and greater in spoils.”
that a Mukatib came to him and said: “Indeed I am not capable of my Kitabah so aid me.” He said: “Should I not teach you words that the Messenger of Allah (ﷺ) taught me? If you had a debt upon you similar to the mountain of Sir, Allah would fulfill it for you. He said: ‘Say: O Allah, suffice me with Your lawful against Your prohibited, and make me independent of all those besides You (Allāhummakfinī biḥalālika `an ḥarāmika, wa aghninī bi faḍlika `amman siwāka).’”
