✅ Answer: Regarding praying in a cemetery, pay attention to the following narration:

مُحَمَّدُ بْنُ یَعْقُوبَ عَنْ مُحَمَّدِ بْنِ یَحْیَی عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ أَحْمَدَ بْنِ الْحَسَنِ عَنْ عَمْرِو بْنِ سَعِیدٍ عَنْ مُصَدِّقٍ عَنْ عَمَّارٍ عَنْ أَبِی عَبْدِ اللَّهِ فِی حَدِیثٍ قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ یُصَلِّی بَیْنَ الْقُبُورِ قَالَ لَا یَجُوزُ ذَلِکَ إِلَّا أَنْ یَجْعَلَ بَیْنَهُ وَ بَیْنَ الْقُبُورِ إِذَا صَلَّی عَشَرَةَ أَذْرُعٍ مِنْ بَیْنِ یَدَیْهِ وَ عَشَرَةَ أَذْرُعٍ مِنْ خَلْفِهِ وَ عَشَرَةَ أَذْرُعٍ عَنْ یَمِینِهِ وَ عَشَرَةَ أَذْرُعٍ عَنْ یَسَارِهِ ثُمَّ یُصَلِّی إِنْ شَاءَ

📚 *Al-Kafi*, Vol. 3, p. 390

Translation: In a narration, Ammar said: I asked Imam al-Sadiq (AS) about a man who prays among the graves. The Imam replied: This action is not permissible unless, when he prays, he places a distance of ten arm lengths (about five meters) from the graves in front, ten arm lengths behind, ten arm lengths on the right, and ten arm lengths on the left. Only then can he pray.

✅ Note: However, in a few narrations, including the two below, permission for this act is granted with a condition, and it can be followed:

مُحَمَّدُ بْنُ الْحَسَنِ بِإِسْنَادِهِ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ بْنِ یَحْیَی عَنْ مُعَاوِیَةَ بْنِ حُکَیْمٍ عَنْ مُعَمَّرِ بْنِ خَلَّادٍ عَنِ الرِّضَا قَالَ لَا بَأْسَ بِالصَّلَاةِ بَیْنَ الْمَقَابِرِ مَا لَمْ یُتَّخَذِ الْقَبْرُ قِبْلَةً

📚 *Tahdhib*, Vol. 2, p. 228

Translation: Imam al-Ridha (AS) said: There is no problem praying between the graves as long as the grave is not made the qibla.

فِی الْعِلَلِ عَنْ مُحَمَّدِ بْنِ مُوسَی بْنِ الْمُتَوَکِّلِ عَنْ عَلِیِّ بْنِ إِبْرَاهِیمَ عَنْ أَبِیهِ عَنْ حَمَّادٍ عَنْ حَرِیزٍ عَنْ زُرَارَةَ عَنْ أَبِی جَعْفَرٍ قَالَ قُلْتُ لَهُ الصَّلَاةُ بَیْنَ الْقُبُورِ قَالَ بَیْنَ خَلَلِهَا وَ لَا تَتَّخِذْ شَیْئاً مِنْهَا قِبْلَةً فَإِنَّ رَسُولَ اللَّهِ صلی الله علیه و آله نَهَی عَنْ ذَلِکَ...

📚 *Al-'Ilal al-Sharay'a*, Vol. 2, p. 358

Translation: Zurara said: I asked Imam al-Baqir (AS), 'How about praying among the graves?' He said: Pray in the spaces between the graves and do not make any grave your qibla, for the Messenger of God (PBUH) has prohibited this....

✅ It is observed that making a grave the qibla and praying directly towards it is strictly forbidden, but praying in the spaces between the graves is permitted.
