690 - وَقَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «كَانَ مَسْجِدُ رَسُولِ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ عَلَى عَهْدِهِ عِنْدَ اَلْمَنَارَةِ اَلَّتِي فِي وَسَطِ اَلْمَسْجِدِ وَ فَوْقُهَا إِلَى اَلْقِبْلَةِ نَحْواً مِنْ ثَلاَثِينَ ذِرَاعاً وَ عَنْ يَمِينِهَا وَ عَنْ يَسَارِهَا وَ خَلْفِهَا نَحْوٌ مِنْ ذَلِكَ فَتَحَرَّ ذَلِكَ وَ إِنِ اِسْتَطَعْتَ أَنْ يَكُونَ مُصَلاَّكَ فِيهِ فَافْعَلْ فَإِنَّهُ صَلَّى فِيهِ أَلْفُ نَبِيٍّ وَ إِنَّمَا سُمِّيَ اَلْخَيْفَ لِأَنَّهُ مُرْتَفِعٌ عَنِ اَلْوَادِي وَ مَا اِرْتَفَعَ عَنْهُ يُسَمَّى خَيْفاً.
Hadith.690 - Imam Jafar ibn Muhammad Al-Sadiq (as) said: "The Mosque of the Messenger of Allah (sw) during his time extended near the minaret located at the center of the mosque, and above it towards the Qibla, approximately thirty cubits, as well as a similar distance to its right, left, and behind. So, focus on this area, and if you can make your place of prayer within it, then do so, for one thousand prophets have prayed there. It was called 'al-Khayf' because it is elevated above the valley, and anything that rises above it is called 'Khayf.'"
