Explanation

The Prophet (may Allah's peace and blessings be upon him) informs us that Allah is extremely pleased with His slave's return to Him by obeying Him and fulfilling His commands, sincerely from his heart. His pleasure is more than the pleasure of a person who was in a desert with no one around him – no water, food, or people – and he lost his camel. He looked for it but failed to find it. So he went to lie under a tree awaiting death. He lost hope in finding his camel and lost hope in life, for his food and drink were on the back of his lost camel. Then suddenly, in this state of hopelessness, he finds his camel right in front of him, its reins attached to the same tree he slept beneath. What is comparable to such happiness? No one can truly relate to such joy except one who was in the same situation. Indeed, it is great joy; joy of life after death. For this reason he took hold of its reins and cried, "O Allah, You are my slave and I am Your Lord!" He wanted to praise Allah saying: "O Allah, You are my Lord and I am Your slave!" but due to his extreme joy, he confused his words.
