Numan bin Bashir reported,

I believe this is from the Messenger of Allah ﷺ, who said, "A man was traveling through a barren land," (Hasan said in his version, meaning a desolate wilderness) "and he stopped under a tree with his riding camel, on which were his waterskin and his food. When he awoke, he did not find it. He climbed a high spot but could not see it. Then he climbed another high spot but could not see it. Then he turned around, and there it was, dragging its halter. He was not more overjoyed at finding it than Allah is at the repentance of His servant when he repents."Bahz said, "His servant when he repents to Him."Bahz said that Hammad said, "I believe it is from the Prophet ﷺ."

حدثنا حسن وبهز المعنى قالا حدثنا حماد بن سلمة عن سماك بن حرب

عن النعمان بن بشير قال

أظنه عن رسول الله ﷺ قال سافر رجل بأرض تنوفة قال حسن في حديثه يعني فلاة فقال تحت شجرة ومعه راحلته وعليها سقاؤه وطعامه فاستيقظ فلم يرها فعلا شرفا فلم يرها ثم علا شرفا فلم يرها ثم التفت فإذا هو بها تجر خطامها فما هو بأشد بها فرحا من الله بتوبة عبده إذا تاب قال بهز عبده إذا تاب إليه قال بهز قال حماد أظنه عن النبي ﷺ
