Indeed, prayers are a time-bounded obligation upon Muslims. The times of prayers are fixed hours, and the best deed a Muslim does is to offer the prayers at the beginning of their stated fixed times.
Allaah تعالى says:
إِنَّ الصَّلَاةَ كَانَتْ عَلَى الْمُؤْمِنِينَ كِتَابًا
مَّوْقُوتًا
`Abdullaah Ibn Mas`ood رضي الله عنه said: I asked the Prophet ﷺ:
“Which deed is most loved by Allaah?” He ﷺ replied: ❝(To offer) the prayer at its
proper time.❞
[Saheeh al-Bukhaaree (527, 5970, 7534) and Saheeh Muslim. In al-Adab al-Mufrad, the very first Hadeeth that Imaam al-Bukhaaree reported is this one. As if to say that the foundation of all good manners begins with having good manners with Allaah]
In another narration, the wording is: ❝To
offer the prayers at their stated fixed times.❞
[Saheeh al-Bukhaaree (2782)]
