Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ كَانَ مَسْجِدُ رَسُولِ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ عَلَى عَهْدِهِ عِنْدَ اَلْمَنَارَةِ اَلَّتِي فِي وَسَطِ اَلْمَسْجِدِ وَ فَوْقُهَا إِلَى اَلْقِبْلَةِ نَحْوَ ثَلاَثِينَ ذِرَاعاً وَ عَنْ يَمِينِهَا وَ عَنْ يَسَارِهَا وَ خَلْفِهَا نَحْوُ ذَلِكَ ».
"The Mosque of the Messenger of Allah سبحانه وتعالى, peace and blessings be upon him and his family, during his time, extended from the minaret in the middle of the mosque and beyond it toward the Qibla for about thirty cubits, as well as to its right, left, and behind it, approximately the same distance."
