From Sahih Muslim (Hadith 4102):
Jabir b. 'Abdullah (Allah be pleased with them) reported:We were with Allah's Messenger (ﷺ) in a journey and my camel meant for carrying water lagged behind. The rest of the hadith is the same and it is mentioned also: Allah's Messenger (ﷺ) pricked it and then said to me: Ride in the name of Allah. He constantly made addition (in prayers for me) and went on saying. May Allah forgive you
