"The Prophet was asked: 'Which deed is the best?' So he said: 'Salat in the beginning of its time.'"  

عَنْ عَمَّتِهِ أُمِّ فَرْوَةَ وَكَانَتْ مِمَّنْ بَايَعَتِ النَّبِيَّ ﷺ قَالَتْ سُئِلَ النَّبِيُّ ﷺ أَىُّ الأَعْمَالِ أَفْضَلُ قَالَ الصَّلاَةُ لأَوَّلِ وَقْتِهَا  

the Prophet said to him: 'Ali! Three are not to be delayed: Salat when its time comes, a funeral whet it (a prepared body) is present, and the (marriage of a) single woman when there is an equal for her."  

أَنَّ النَّبِيَّ ﷺ قَالَ لَهُ يَا عَلِيُّ ثَلاَثٌ لاَ تُؤَخِّرْهَا الصَّلاَةُ إِذَا آنَتْ وَالْجَنَازَةُ إِذَا حَضَرَتْ وَالأَيِّمُ إِذَا وَجَدْتَ لَهَا كُفْؤًا  

Messenger of Allah said: "The beginning of the time for Salat is pleasing to Allah, and the end of its time is pardoned by Allah."  

قَالَ رَسُولُ اللَّهِ ﷺ الْوَقْتُ الأَوَّلُ مِنَ الصَّلاَةِ رِضْوَانُ اللَّهِ وَالْوَقْتُ الآخِرُ عَفْوُ اللَّهِ  

"A man said to Ibn Mas'ud: 'Which deed is most virtuous?' He said: 'I asked Messenger of Allah (that). He said: "Salat at the beginning of its time." I asked him: "What is after that O Messenger of Allah?" He said: "Being dutiful to one's parents." I said: "What is after that [O Messenger of Allah]?" He said: "Jihad in the Way of Allah."  

سَأَلْتُ عَنْهُ رَسُولَ اللَّهِ ﷺ فَقَالَ الصَّلاَةُ عَلَى مَوَاقِيتِهَا قُلْتُ وَمَاذَا يَا رَسُولَ اللَّهِ قَالَ وَبِرُّ الْوَالِدَيْنِ قُلْتُ وَمَاذَا يَا رَسُولَ اللَّهِ قَالَ وَالْجِهَادُ فِي سَبِيلِ اللَّهِ  

"Messenger of Allah did not pray any Salat at the end of its time two times, until Allah took him."  

مَا صَلَّى رَسُولُ اللَّهِ ﷺ صَلاَةً لِوَقْتِهَا الآخِرِ مَرَّتَيْنِ حَتَّى قَبَضَهُ اللَّهُ
