"O ye who believe! Avoid suspicion as much (as possible): for suspicion in some cases is a sin: and spy not on each other nor speak ill of each other behind their backs." (The Holy Quran, Chapter 49, Verse 12)

The Prophet Muhammad (peace be upon him) said: "Eat together and not separately, for the blessing is associated with the company." (Al-Tirmidhi, Hadith 1137)
