Narrated Isma`il: I asked `Abdullah bin Abi `Aufa, "Did the Prophet give glad tidings to Khadija?" He said, "Yes, of a palace of Qasab (in Paradise) where there will be neither any noise nor any fatigue."

Hadith Commentary: Two characteristics of the palace in Paradise have been mentioned: that there will be neither noise nor fatigue, etc., in it. The relevance of these two characteristics is that when the Messenger of Allah (sallallahu alayhi wa sallam) invited Khadijah (radi Allahu anha) to Islam, she accepted it with utmost happiness and openness of heart; there was no occasion for commotion, uproar, or dispute, nor did she experience any kind of discomfort in this matter. Rather, by her embracing faith, the Messenger of Allah (sallallahu alayhi wa sallam) found great tranquility, and his life partner supported him in every possible way. (Fath al-Bari: 7/174)
