“Once, a man said to abu ‘Abd Allah (a.s.), when I was present, saying, ‘I performed al-‘Umrah in al-Haram months (the Sacred months). Now I have come to perform al-Hajj al-Tamattu‘ (advantageous).’ I heard abu ‘Abd Allah (a.s.), say, ‘What you have done is very good. We do not compromise with the book of Allah, most Majestic, most Glorious, and the Sunnah of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to your cause. When our Lord will resurrect us and we will be brought before Him we will say, O our Lord we followed Your book and the Sunnah of Your Holy prophet. People will say, O Lord, we looked into our opinions and followed them, then Allah, most Majestic, most Glorious, will do with us and with them as He wills.’””
