“I prayed two rak’ahs with the Messenger of Allah (ﷺ) on a journey, and two rak’ahs with Abu Bakr, and two rak’ahs with ‘Umar, may Allah (SWT) be pleased with them both.”
“I heard ‘Umar say: ‘I gave a horse to someone to ride in the cause of Allah, the Mighty and Sublime, and the one who kept it neglected it. I wanted to buy it back from him, and I thought that he would sell it at a cheap price. I asked the Messenger for Allah about that and he said: Do not buy it, even if he gives it to you for a Dirham. The one who takes back his charity is like the dog that goes back to its own vomit. “‘
“I said: ‘O Messenger of allah, shall we not go out and fight in jihad with you, for I do not think there is any deed in the qur’an that is better than jihad.’ He said: ‘No. the best and most beautiful (type) of jihad is Hajj to the House; Hajj Al-Mabrur. ”(sahih)
