Zaid b. Thabit (Allah be pleased with him) said: We took meal shortly before dawn along with the Messenger of Allah (may peace be upon him). We then stood up for prayer. I said: How much span of time was there between the two (acts, i.e. taking of Sahri and observing of prayer)? He said (a span of reciting) fifty verses.
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.
