Chapter : Excellence of taking meal before dawn, stress on giving It preference and preference for deferring it (at the fag end of the night) and hastening in breaking it.

Anas (Allah be pleased with him) reported Allah’s Messenger (may peace be upon him) as saying: Take meal a little before dawn, for there is a blessing in taking meal at that time.
