It is narrated from Qasim bin Muhammad that he said: I was with Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) when a man came to him and said: "I intend to travel." Abdullah bin Umar (may Allah be pleased with them both) said: "Wait, so that I may bid you farewell just as the Messenger of Allah (peace and blessings be upon him) used to bid us farewell: 'Astawdi'u Allaha dinaka wa amanataka wa khawatima 'amalika' (I entrust to Allah your religion, your trust and the final outcomes of your deeds)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Qaza'ah that Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said to me: "I bid you farewell just as the Messenger of Allah (peace and blessings be upon him) bade me farewell: 'Astawdi'u Allaha dinaka wa amanataka wa khawatima 'amalika' (I entrust to Allah your religion, your trust and the final outcomes of your deeds)."

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that a man came to the Prophet (peace and blessings be upon him) and said: "O Messenger of Allah! I intend to travel, so give me some provision (a supplication)." He (peace and blessings be upon him) said: "May Allah provide you with taqwa (God-consciousness) as your provision." The man said: "Give me more." He said: "And may Allah forgive your sins." The man said: "May my father and mother be ransomed for you! Give me more." He (peace and blessings be upon him) said: "And may Allah make good easy for you wherever you may be."

It is narrated from Muhammad bin Ka'b al-Qurazi that Sayyiduna Abdullah bin Yazid (may Allah be pleased with him) was invited to a meal. When he came, he said: When the Messenger of Allah (peace and blessings be upon him) bade farewell to an army, he would supplicate: 'Astawdi'u Allaha dinakum wa amanatakum wa khawatima a'malikum' (I entrust to Allah your religion, your trust and the final outcomes of your deeds).
