BismAllah ArRahman ArRahim

And surely this your religion is one religion and I am your Lord, therefore be careful (of your duty) to Me.
اور بیشک یہ تمہارا دین ایک ہی دین ہے (ف۸۴) اور میں تمہارا رب ہوں تو مجھ سے ڈرو،

~ Qur'an (23:52)

Admonish your brother (comrade) by good deeds and kind regards, and ward off his evil by favouring him.

~ Imam Ali Ibne AbiTalib (as) [Nehaj-ul-Balagha]
