وَ رَوَى أَبُو حَمْزَةَ اَلثُّمَالِيُّ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «مَنْ صَلَّى فِي مَسْجِدِ اَلْخَيْفِ بِمِنًى مِائَةَ رَكْعَةٍ قَبْلَ أَنْ يَخْرُجَ مِنْهُ عَدَلَتْ عِبَادَةَ سَبْعِينَ عَاماً وَ مَنْ سَبَّحَ اَللَّهَ فِيهِ مِائَةَ تَسْبِيحَةٍ كَتَبَ اَللَّهُ لَهُ كَأَجْرِ عِتْقِ رَقَبَةٍ وَ مَنْ هَلَّلَ اَللَّهَ فِيهِ مِائَةَ تَهْلِيلَةٍ عَدَلَتْ أَجْرَ إِحْيَاءِ نَسَمَةٍ وَ مَنْ حَمَّدَ اَللَّهَ فِيهِ مِائَةَ تَحْمِيدَةٍ عَدَلَتْ أَجْرَ خَرَاجِ اَلْعِرَاقَيْنِ يُتَصَدَّقُ بِهِ فِي سَبِيلِ اَللَّهِ عَزَّ وَ جَلَّ.
Abu Hamza al-Thumali narrated from Imam Muhammad ibn Ali Al-Baqir (a.s) that He said: "Whoever prays one hundred rak'ahs in the Mosque of al-Khayf in Mina before leaving it, it is equivalent to the worship of seventy years. Whoever glorifies (says 'SubhanAllah (swt)') one hundred times in it, Allah (swt) records for them the reward of freeing a slave. Whoever declares the oneness of Allah (swt) (says 'La ilaha illa Allah (swt)') one hundred times in it, it is equivalent to the reward of reviving a soul. Whoever praises Allah (swt) (says 'Alhamdulillah') one hundred times in it, it is as if they have given in charity the value of the entire wealth of Iraq and its surroundings in the path of Allah (swt), the Mighty and Majestic."
