Mukhtasar Muslim

It is narrated from Sayyiduna Abu Musa (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) sent him and Sayyiduna Mu'adh (may Allah be pleased with him) towards Yemen, and said: Make things easy and do not make them difficult and harsh, and give glad tidings and do not make people averse, and work together in agreement and do not create discord.
