The hallmarks of perfection in faith is being best in character, being altruistic, selfless, and being friendly to others
"The most perfect of the believers in their Īman (faith) are the ones who are best in character and those who lower their necks ˹for others˺. They are the ones who befriend and are friendly ˹to others˺. There is no goodness in those who do not befriend and are not friendly."
"أكمَلُ المؤمنين إيمانًا أحسَنُهم خلُقًا، الموطئون أكنافًا. الذين يألَفون. ويُؤْلفون، وَلَا خَيرَ فيمن لا يألفُ. ولا يُؤْلفُ".
