One day Prophet Muhammad (s.a.w.) noticed a Bedouin leaving his camel
without tying it and he asked the Bedouin, "Why don't you tie down
your camel?" The Bedouin answered, "I put my trust in Allah." The
Prophet then said, "Tie your camel first, then put your trust in
Allah". This hadith was reported by At-temizi and Ibn Majah.
