Merit of Suhur (Predawn meal in Ramadan) and the Excellence of Delaying having it till before Dawn

Zaid bin Thabit (May Allah be pleased with him) reported:
We took Suhur (predawn meal) with the Messenger of Allah ﷺ and then we stood up for (Fajr) Salat (prayer). It was asked: "How long was the gap between the two?" He replied: "The time required for the recitation of fifty Ayat."

[Al-Bukhari and Muslim].

وعن زيد بن ثابت رضي الله عنه قال: تسحرنا مع رسول الله ﷺ ثم قمنا إلى الصلاة قيل كم كان بينهما؟ قال: خمسون آية ((متفق عليه))

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].

وعن ابن عمر رضي الله عنهما قال: كان لرسول الله ﷺ مؤذنان: بلال وابن أم مكتوم. فقال رسول الله ﷺ " إن بلالا يؤذن بليل فكلوا واشربوا حتى يؤذن ابن أم مكتوم" قال ولم يكن بينهما إلا أن ينزل هذا ويرقى هذا، ((متفق عليه))

'Amr bin Al-'As (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said, "The difference between our observance of Saum (fasting) and that of the people of the Scriptures is Suhur (predawn meal in Ramadan)."

[Muslim].

وعن عمرو بن العاص رضي الله عنه أن رسول الله قال: "فصل ما بين صيامنا وصيام أهل الكتاب أكلة السحر. ((رواه مسلم)).
