It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "A little understanding of the religion is better than a great deal of worship. It is enough understanding for a man that he worships Allah, and it is enough ignorance for a man that he is pleased with his own opinion. People are of only two kinds: the believer and the ignorant. So do not harm the believer, and do not live as a neighbour to the ignorant."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Raja' bin Haywah except Ishaq Abu Abd al-Rahman; al-Layth is alone in narrating it."
