It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Look for trustworthiness among Quraysh," or he (peace and blessings be upon him) said: "Seek out trustworthiness among Quraysh, for the trustworthy man of Quraysh has double the merit of the trustworthy man of others, and the strong man of Quraysh has double the merit of the strong man of others."
