It is narrated from Sayyiduna Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to teach us the sermon for a need (khutbat al-hajah), saying: "Inna al-hamda lillahi nahmaduhu wa nasta'inuh, wa na'udhu billahi min shururi anfusina wa min sayyi'ati a'malina, man yahdihillahu fala mudilla lah, wa man yudlil fala hadiya lah, wa ashhadu an la ilaha illallahu wahdahu la sharika lah, wa ashhadu anna Muhammadan 'abduhu wa rasuluh" (Indeed all praise belongs to Allah; we praise Him and seek His help, and we seek refuge in Allah from the evils of our own selves and from our bad deeds. Whomever Allah guides, there is none to lead him astray, and whomever He leaves astray, there is none to guide him. I bear witness that there is no true god except Allah, alone, without partner, and I bear witness that Muhammad (peace and blessings be upon him) is His servant and His Messenger). Abu Ubaydah (may Allah have mercy on him) relates that he heard Sayyiduna Abu Musa (may Allah be pleased with him) saying that the Messenger of Allah (peace and blessings be upon him) used to say: "If you wish to connect your sermon with verses of the Book of Allah, then recite (these verses): (Fear Allah as He should be feared, and do not die except as Muslims) [Al Imran: 102], (Fear Allah, through whom you ask one another, and (respect) the wombs (kinship); indeed Allah is ever watchful over you) [al-Nisa': 1], (Fear Allah and speak words of appropriate justice; He will amend your deeds for you and forgive you your sins. And whoever obeys Allah and His Messenger has certainly attained a great achievement) [al-Ahzab: 70-71]. After this say 'Amma ba'd' (To proceed, after praise and salutations), and then speak about your need."
