Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated ‘Umar (Radi-Allahu ‘anhu):
“If anybody has to take
an oath, he should swear only by Allah.” The people of Quraish used to
swear by their fathers, but the Prophet (Sallallahu ‘Alaihi Wa Sallam)
said, “Do not swear by your fathers.”
