[Machine] The Messenger of Allah ﷺ said, "There are two times when a supplication is not rejected: when the prayer is established at night and in the ranks in the way of Allah."  

الطبراني:٥٧٧٤حَدَّثَنَا مُوسَى بْنُ جُمْهُورٍ التِّنِّيسِيُّ ثنا مُؤَمَّلُ بْنُ إِهَابٍ ثنا أَيُّوبُ بْنُ سُوَيْدٍ حَدَّثَنِي مَالِكُ بْنُ أَنَسٍ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ قَالَ

قَالَ رَسُولُ اللهِ ﷺ «سَاعَتَانِ لَا تُرَدُّ عَلَى دَاعٍ دَعْوَتُهُ حِينَ يُقَامُ اللَّيْلُ صَلَاةً وَفِي الصَّفِّ فِي سَبِيلِ اللهِ»

Collected by Ibn Ḥibbān, Bayhaqī

ذِكْرُ اسْتِحْبَابِ الِاجْتِهَادِ فِي الدُّعَاءِ لِلْمَرْءِ عِنْدَ الْقِيَامِ إِلَى الصَّلَاةِ

[Machine] The Messenger of Allah ﷺ said, "There are two times when the prayer of a person is not rejected: when the prayer is being called and during the line in the path of Allah."  

ابن حبّان:١٧٦٤أَخْبَرَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ الْمُؤْمِنِ بِجُرْجَانَ قَالَ حَدَّثَنَا مُؤَمَّلُ بْنُ إِهَابٍ قَالَ حَدَّثَنَا أَيُّوبُ بْنُ سُوَيْدٍ قَالَ حَدَّثَنَا مَالِكٌ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ «سَاعَتَانِ لَا تُرَدُّ عَلَى دَاعٍ دَعْوَتُهُ حِينَ تُقَامُ الصَّلَاةُ وَفِي الصَّفِّ فِي سَبِيلِ اللَّهِ»

[Machine] Two hours in which the gates of heaven are opened, and a supplicant who is not responded to by his request is rare, with the presence of the caller through prayer and lining up in the way of Allah.  

البيهقي:١٩٣٩أَخْبَرَنَا أَبُو أَحْمَدَ الْمِهْرَجَانِيُّ ثنا أَبُو بَكْرِ بْنُ جَعْفَرٍ الْمُزَكِّي ثنا مُحَمَّدُ بْنُ إِبْرَاهِيمَ ثنا ابْنُ بُكَيْرٍ ثنا مَالِكٌ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ قَالَ

سَاعَتَانِ تُفْتَحُ فِيهِمَا أَبْوَابُ السَّمَاءِ وَقَلَّ دَاعٍ تُرَدُّ عَلَيْهِ دَعْوَتُهُ حَضْرَةُ النِّدَاءِ بِالصَّلَاةِ وَالصَّفُّ فِي سَبِيلِ اللهِ
