Shaqayq bin Salmah al-Asadi شقيق بن سلمة الأسدي أبو وائل الكوفي · The Book of Jihad

"A man asked the Messenger of Allah (ﷺ) which deed is best. He said: 'Faith in Allah.' He said: 'Then what?' He said: 'Jihad in the cause of Allah.' He said: 'Then what?' He said: 'Hajjun Mabrur.'" Hajj, that is accepted, or free of sin.
