لا يكون المؤمن مؤمنا حتى يرضى لأخيه ما يرضى لنفسه
One will not be a true believer until he wishes for his brother that which he wishes for himself.
If one has to practise on this Hadith and inculcate its teaching in his life, then all internal disputes and arguments will come to an end. However, when we wish to receive more while we wish for others to receive less, then how can these quarrels ever be resolved? (Suhbat Baa Awliyaa pg. 96)
