Narrated Ubai bin Ka 'b: Allah' s Messenger (ﷺ) said, "Moses the Messenger of Allah," and then he narrated the whole story about him. Al-Khadir said to Moses, "Did not I tell you that you can have no patience with me." ( 18.72). Moses then violated the agreement for the first time because of forgetfulness, then Moses promised that if he asked Al-Khadir about anything, the latter would have the right to desert him. Moses abided by that condition and on the third occasion he intentionally asked Al-Khadir and caused that condition to be applied. The three occasions referred to above are referred to by the following Verses: "Call me not to account for forgetting And be not hard upon me." ( 18.73) "Then they met a boy and Khadir killed him." ( 18.74) "Then they proceeded and found a wall which was on the verge of falling and Khadir set it up straight." ( 18.77)
