Chapter 16: The Book of Pilgrimage
Ibn Abbas (Allah be pleased with them) reported that a woman fell ill and she said: In case Allah cures me I will certainly go and observe prayer in Bait al-Maqdis. She recovered and so she made preparations to go out (to that place). She came to Maimuna. the wife of Allah' s Apostle (ﷺ). and after greeting her she informed her about it, whereupon she said: Stay here. and eat the provision (which you had made) and observe prayer In the mosque of the Messenger (ﷺ). for I heard Allah' s Messenger (ﷺ) say: Prayer In it is better than a thousand prayers observed in other mosques except the mosque of the Ka' ba.
