Praise be to Allah who urged for fighting in His cause and has promised a successful outcome and decisive victory in return for this. I testify that there is no deity except Allah Alone who has no partner, and who says in His Glorious Book: and (as for) the believers, it was incumbent upon Us to help (them). I testify that Muhammad is His servant, Messenger and His Khalil (beloved Servant) who was the best of Mujahids, the most sincere supporter, and the most truthful to His servants. Peace be upon him, his good, and purified family and his honorable Companions who dedicated themselves to Allah (Exalted be He) and fought for His Cause until He made His religion prevail by their efforts. He made the believers superior and the disbelievers inferior by them (may Allah be pleased with them, honor their final end, and made us of their followers in righteousness until the Day of Recompense.)
March forth, whether you are light (being healthy, young and wealthy) or heavy (being ill, old and poor), and strive hard with your wealth and your lives in the Cause of Allâh. This is better for you, if you but knew.
May Allâh forgive you (O Muhammad ﺻﻠﻰ ﺍﷲ ﻋﻠﻴﻪ ﻭﺳـﻠﻢ). Why did you grant them leave (for remaining behind; you should have persisted as regards your order to them to proceed on Jihâd )
To guard Muslims from the disbelievers in Allah's Cause for one day is better than the world and whatever is in it, and a place in Paradise as small as that occupied by the whip of one of you is better than the world and whatever is in it; and a morning's or an evening's journey which a slave (person) travels in Allah's Cause is better than the world and whatever is in it.
