The Importance of Masla Ha in Islamic Law

Umar ibn al-Khatab responded well lahi I know that the Rahi or the opinion of the Prophet Salaam is always more blessed than my opinion. These people would have remained hypocrites but now those people if I were to tell them to kill Abdullah Ibn Ubay they'd be the first ones to do it right their iman had now increased and they were now true believers. The issue of Masla ha is one of the sources of Islamic law and these days especially a lot is being written about it.
