Virtue of praying in the Prophet’s Mosque
Hadith 565
وَبِهَذَا، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: ((وَالَّذِي نَفْسِي بِيَدِهِ لَصَلَاةٌ فِي مَسْجِدِ الْمَدِينَةِ أَفْضَلُ مِنْ أَلْفِ صَلَاةٍ فِيمَا سِوَاهُ لَيْسَ الْكَعْبَةَ)).
With this same chain: The Messenger of Allah, peace and blessings be upon him, said: "By the One in Whose hand is my soul! Performing one prayer in the mosque of Madinah (the Prophet's Mosque) is better than performing a thousand prayers in other mosques, except for the Ka'bah (the Sacred Mosque in Makkah)."
