Conciliating Between People
Umm Kulthum bint Uqbah (radi Allahu anha) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, ‘The person who (lies) in order to conciliate between people is not a liar, when he conveys good or says (something) good.”
[Sahih al-Bukhari and Muslim]
This Hadith tells us a very important principle, that is, in spite of its being unlawful, one is permitted to tell a lie if one has to do it for reforming one’s society or family or in the interest of Muslims in general. If two Muslim brothers are estranged and someone communicates to them such things which are likely to remove conflict and resentment between them, promote mutual love and bring them nearer to each other, such action, even if it has a lie, is not called a lie in Islam.
And Allah Knows Best!
