✅Answer:
Please pay attention to the following narrations:
1 عَنْ أَبِی بَصِیرٍ عَنْ أَبِی عَبْدِ اللَّهِ سَأَلْتُهُ عَنْ رَجُلٍ صَلَّی وَ فِی ثَوْبِهِ جَنَابَةٌ أَوْ دَمٌ حَتَّی فَرَغَ مِنْ صَلَاتِهِ ثُمَّ عَلِمَ قَالَ مَضَتْ صَلَاتُهُ وَ لَا شَیْ ءَ عَلَیْهِ
📚 Al-Kafi, vol. 3, p. 405
Abu Basir said: I asked Imam Sadiq, peace be upon him, about a person who prays while there is semen or blood on his clothes until he finishes the prayer and then becomes aware; The Imam said: His prayer is complete, and he does not have to do anything.
2 عَنْ عَبْدِ اللَّهِ بْنِ سِنَانٍ قَالَ سَأَلْتُ أَبَا عَبْدِ اللَّهِ عَنْ رَجُلٍ أَصَابَ ثَوْبَهُ جَنَابَةٌ أَوْ دَمٌ قَالَ إِنْ کَانَ عَلِمَ أَنَّهُ أَصَابَ ثَوْبَهُ جَنَابَةٌ قَبْلَ أَنْ یُصَلِّیَ ثُمَّ صَلَّی فِیهِ وَ لَمْ یَغْسِلْهُ فَعَلَیْهِ أَنْ یُعِیدَ مَا صَلَّی وَ إِنْ کَانَ لَمْ یَعْلَمْ بِهِ فَلَیْسَ عَلَیْهِ إِعَادَةٌ
📚 Al-Kafi, vol. 3, p. 406
Abdullah ibn Sinan said: I asked Imam Sadiq, peace be upon him, about a person whose clothes have been stained with semen or blood; The Imam said: If he knew and was aware that semen had gotten on his clothes before he prayed and then he prayed in it without washing it, then it is his duty to repeat the prayers that he has prayed in it. And if he did not know (that it was impure), he does not have to repeat the prayer.
3 عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِی عَبْدِ اللَّهِ قَالَ سَأَلْتُ أَبَا عَبْدِ اللَّهِ عَنِ الرَّجُلِ یُصَلِّی وَ فِی ثَوْبِهِ عَذِرَةٌ مِنْ إِنْسَانٍ أَوْ سِنَّوْرٍ أَوْ کَلْبٍ أَ یُعِیدُ صَلَاتَهُ قَالَ إِنْ کَانَ لَمْ یَعْلَمْ فَلَا یُعِیدُ
📚 Al-Tahdheeb, vol. 2, p. 359
Translation: Abd al-Rahman said: I asked Imam Sadiq, peace be upon him, about a person who prays while there is human impurity or cat or dog impurity on his clothes; Does he have to repeat his prayer? The Imam said: If he did not know, he does not have to repeat the prayer.
4 عَنِ الْعِیصِ بْنِ الْقَاسِمِ قَالَ سَأَلْتُ أَبَا عَبْدِ اللَّهِ عَنْ رَجُلٍ صَلَّی فِی ثَوْبِ رَجُلٍ أَیَّاماً ثُمَّ إِنَّ صَاحِبَ الثَّوْبِ أَخْبَرَهُ أَنَّهُ لَا یُصَلَّی فِیهِ قَالَ لَا یُعِیدُ شَیْئاً مِنْ صَلَاتِهِ
📚 Al-Tahdheeb, vol. 2, p. 360
Ays ibn Qasim said: I asked Imam Sadiq, peace be upon him, about a person who has prayed in someone else's clothes for a few days, and then the owner of the clothes informs him that the prayer cannot be performed in those clothes (and they were impure); The Imam said: He does not have to repeat any of his prayers.
✅The above narrations apply to a situation where a person has no knowledge of the impurity of his clothes and has prayed in them, and after praying, he becomes aware of the impurity of his clothes. In such a case, there is no need to repeat the past prayers. From this point on, he either purifies his clothes or changes them and performs the next prayers.
✅Any change in the form of the question will cause a difference in its answer, for example, if the person was aware of the impurity of the clothes but forgot about it at the time of the prayer, or if he becomes aware of the impurity of his clothes during the prayer, in these cases, the answer to the question will be different.

اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ
وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْرَ
