It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever pleases a ruler at the cost of the displeasure of his Lord, the Mighty and Majestic, has left the religion of Allah." Allaq bin Abi Muslim is alone in narrating this, and all the narrators up to him are trustworthy (thiqah). Here the Book of Rulings (Kitab al-Ahkam) is complete.
