They well know that prayer at another time than this is more excellent, for Messenger of Allah ﷺ said: The prayer of those who are penitent is observed when your weaned camels feel the heat of the sun.  

أَنَّ الصَّلاَةَ فِي غَيْرِ هَذِهِ السَّاعَةِ أَفْضَلُ إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ صَلاَةُ الأَوَّابِينَ حِينَ تَرْمَضُ الْفِصَالُ  

They well know that prayer at another time than this is more excellent, for Messenger of Allah ﷺ said: The prayer of those who are penitent is observed when your weaned camels feel the heat of the sun. (Using translation from Muslim 748a)  

أَنَّ الصَّلَاةَ فِي غَيْرِ هَذِهِ السَّاعَةِ أَفْضَلُ إِنَّ رَسُولَ اللهِ ﷺ قَالَ إِنَّ صَلَاةَ الْأَوَّابِينَ حِينَ تَرْمَضُ الْفِصَالُ  

[Machine] "He saw a group of people praying the Duha prayer in Masjid Quba, so he said, 'They have learned that praying at a time other than this hour is better. Indeed, the Prophet ﷺ said, 'The prayer of the devout believers is when the camels young ones lose their tails."  

أَنَّهُ رَأَى قَوْمًا يُصَلُّونَ الضُّحَى فِي مَسْجِدِ قُبَاءَ فَقَالَ لَقَدْ عَلِمُوا أَنَّ الصَّلَاةَ فِي غَيْرِ هَذِهِ السَّاعَةِ أَفْضَلُ إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ «صَلَاةُ الْأَوَّابِينَ حِينَ تَرْمَضُ الْفِصَالُ»  

[Machine] "That prayer in any other time is better, for indeed the Messenger of Allah ﷺ said: 'Verily the prayer of the Awabeen (devoted worshippers) is when the camels are tied up (i.e. at sunset).' And he ﷺ also said: 'One time, there were people who used to perform prayer.'"  

أَنَّ الصَّلَاةَ فِي غَيْرِ هَذِهِ السَّاعَةِ أَفْضَلُ إِنَّ رَسُولَ اللهِ ﷺ قَالَ إِنَّ صَلَاةَ الْأَوَّابِينَ حِينَ تَرْمَضُ الْفِصَالُ وَقَالَ مَرَّةً وَأُنَاسًا يُصَلُّونَ
