On the authority of Abu Hurayrah (may Allah be pleased with him) who said: The Messenger of Allah (peace be upon him) said:
"Part of the perfection of one's Islam is his leaving that which does not concern him."
The most overlooked aspect of completing and perfecting our practice of Islam is explained in this Hadith. Interfering and poking our nose in other people’s matters is not only the cause of many quarrels and disputes but also disturbs your peace of heart. The hadith clearly explains that we should not bother ourselves with the matters that do not concern us. Half of the problems in your life would be solved by acting on the Hadith.
Acceptance is the key to a peaceful life. We must not concern ourselves with the things that are not in our control. Whatever is decided by Allah, it will happen no matter what we say or how much we criticize. Criticism and bad mouthing, if something is not happening according to your expectations will only result in added negative points in one’s nama-e-amal. Instead, we must focus and set our priorities that concern ourselves. Try making your existence in the world fruitful and productive for other yourself as well as others.
This saying of Holy Prophet (SAWW) outlines a valuable approach to life. This characteristic can be applied in daily life situations. Shaikh Abdul Fattah Abu Ghuddah mentions that even if a person cancels an appointment or meeting with you, still you must not ask for the reason. That is because it may be inappropriate if the person doesn’t wish to explain. You must a high degree of sensitivity and humility. And that is because it is “Part of the perfection of one's Islam”
