وَ رَوَى أَبُو حَمْزَةَ الثُّمَالِيُّ عَنْ أَبِي جَعْفَرٍ ع أَنَّهُ قَالَ- مَنْ صَلَّى فِي الْمَسْجِدِ الْحَرَامِ صَلَاةً مَكْتُوبَةً قَبِلَ اللَّهُ بِهَا مِنْهُ كُلَّ صَلَاةٍ صَلَّاهَا مُنْذُ يَوْمَ وَجَبَتْ عَلَيْهِ الصَّلَاةُ وَ كُلَّ صَلَاةٍ يُصَلِّيهَا إِلَى أَنْ يَمُوتَ.

Hadith.681 - Abu Hamza al-Thumali narrated from Imam Muhammad ibn Ali Al-Baqir (as) that He said: "Whoever performs an obligatory prayer in the Sacred Mosque (Masjid al-Haram), Allah (swt) accepts it as equivalent to every prayer they have performed since the day prayer became obligatory upon them, and every prayer they will perform until they die."
