The Prophet ﷺ said: Two (prayers) are not rejected, or seldom rejected: Prayer at the time of the call to prayer, and (the prayer) at the time of fighting, when the people grapple with each other. Musa said: Rizq ibn Sa'id ibn AbdurRahman reported from AbuHazim on the authority of Sahl ibn Sa'd from the Prophet ﷺ as saying: And while it is raining.  

قَالَ رَسُولُ اللَّهِ ﷺ ثِنْتَانِ لاَ تُرَدَّانِ أَوْ قَلَّمَا تُرَدَّانِ الدُّعَاءُ عِنْدَ النِّدَاءِ وَعِنْدَ الْبَأْسِ حِينَ يُلْحِمُ بَعْضُهُمْ بَعْضًا قَالَ مُوسَى وَحَدَّثَنِي رِزْقُ بْنُ سَعِيدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ عَنِ النَّبِيِّ ﷺ قَالَ وَوَقْتَ الْمَطَرِ  

[Machine] The Prophet of Allah ﷺ said: There are two things that are not rejected or hardly rejected: supplication during the call to prayer and supplication during a battle when soldiers are engaged in fighting each other.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ ثِنْتَانِ لَا تُرَدَّانِ أَوْ قَلَّ مَا تُرَدَّانِ الدُّعَاءُ عِنْدَ النِّدَاءِ وَعِنْدَ الْبَأْسِ حِينَ يُلْحِمُ بَعْضُهُ بَعْضًا  

[Machine] He informed him that the Messenger of Allah ﷺ said, "There are two things that are not rejected, or rarely rejected: supplication when the call for prayer is made, and supplication during times of distress, when people are fighting against each other." Al-Zam'mi raised it, and Imam Malik confirmed it.  

أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ قَالَ اثْنَتَانِ لَا تُرَدَّانِ أَوْ قَلَّمَا تُرَدَّانِ الدُّعَاءُ عِنْدَ النِّدَاءِ وَعِنْدَ الْبَأْسِ حِينَ يُلْحِمُ بَعْضُهُ بَعْضًا رَفَعَهُ الزَّمْعِيُّ وَوَقَفَهُ مَالِكُ بْنُ أَنَسٍ الْإِمَامُ  

"اثنتان لا يُرَدَّان - أَوْ قال: ما يردَّانِ -: الدعاءُ عند القدرِ، وعند البأس، حين يلتحم بعضُهم بعضًا".  

"ثِنْتَانِ لا تُرَدَّان: الدُّعَاءُ عِنْدَ النِّدَاءِ، وَعِنْدَ الْبَأْسِ حِينَ يُلحِمُ بَعْضُهُمْ بَعْضًا".
