Ali bin Rabi’ah said:
“I witnessed Ali having an animal brought to him to ride. When he placed his foot in the stirrup he said: ‘In the Name of Allah,’ (Bismillāh) [three times]. So then, once he had ascended upon its back, he said: ‘All praise is due to Allah.’ (Al-ḥamdulillāh) then he said: Glory is to Him Who has subjected this to us, and we were not able to do it. And, surely, to our Lord are we returning (Subḥān alladhī sakh-khara lanā hādhā wa mā kunnā lahū muqrinīn. Wa innā ilā rabbinā lamunqalibūn). Then he said: ‘All praise is due to Allah (Al-ḥamdulillāh)’ – three times – and ‘Allah is the Greatest (Allāhu Akbar)’ – three times – ‘Glory is to You, indeed I have wronged myself, so forgive me, for indeed none forgives sins except You (Subḥānaka innī qad ẓalamtu nafsī faghfirlī fa-innahū lā yaghfirudh-dhunūba illā ant).’ Then he laughed. So I said: ‘O Commander of the Believer! What caused you to laugh?’ He said: ‘I saw the Messenger of Allah do as I did, then he (ﷺ) laughed, so I said, ‘What cause you to laugh?’ He said: ‘Indeed, your Lord is very pleased with His worshipper when he says: “O my Lord, forgive me my sins, indeed, no one other than You forgives sins.”

Ibn `Umar narrated that:
When the Prophet (ﷺ) wanted to travel, when he mounted his riding camel, he would say the Takbir three times and say: Glory is to Him Who has subjected this to us, and we were not able to do it. And, surely, to our Lord are we returning (Subḥān alladhī sakh-khara lanā hādhā wa mā kunnā lahū muqrinīn. Wa innā ilā rabbinā lamunqalibūn). Then he would say: “O Allah, I ask You in this journey of mine from the righteousness and piety and actions that which you are pleased with. O Allah, ease for us the path, and make near for us the distance of the land. O Allah, You are the companion in the journey, and the caretaker for the family. O Allah, accompany us in our journey, and take care of our families (Allāhumma innī as’aluka fī safarī hādhā minal-birri wat-taqwā, wa minal-`amali mā tarḍā. Allāhumma hawwin `alainal-masīra, waṭwi `annā bu`dal-arḍ. Allāhumma antaṣ-ṣāḥibu fis safari wal-khalīfatu fil-ahli. Allāhumma aṣḥabnā fī safarinā wakhlufnā fī ahlinā).” And when he would return to his family, he would say: “(We are) Returning, if Allah wills, repenting, worshipping, and to our Lord directing the praise (Ā’ibūna in shā’ Allāh, tā’ibūna `ābidūna lirabbinā hāmidūn).”
