Merit of Suhur (Predawn meal in Ramadan) and the Excellence of Delaying having it till before Dawn
وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: كَانَ لِرَسُولِ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ مُؤَذِّنَانِ: بِلاَلٌ وَابْنُ أُمِّ مَكْتُومٍ. فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ إِنَّ بِلاَلاً يُؤَذِّنُ بِلَيْلٍ فَكُلُوا وَاشْرَبُوا حَتَّى يُؤَذِّنَ ابْنُ أُمِّ مَكْتُومٍ قَالَ وَلَمْ يَكُنْ بَيْنَهُمَا إِلاَّ أَنْ يَنْزِلَ هَذَا وَيَرْقَى هَذَا، ((مُتَّفَقٌ عَلَيْهِ))
Ibn 'Umar (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) had two Mu'adhdhin: Bilal and Ibn Umm Maktum (May Allah be pleased with them). The Messenger of Allah (ﷺ) said, "Bilal proclaims Adhan [call to Salat (prayer)] at fag end of night, so eat and drink till Ibn Umm Maktum pronounces Adhan." Ibn 'Umar (May Allah be pleased with them) added: And the gap between their Adhan was not more than the time spent in one's getting down and the other's climbing (the minaret). [Al-Bukhari and Muslim].
