قَالَ سَتَجِدُنِي إِنْ شَاءَ اللَّهُ صَابِرًا وَلَا أَعْصِي لَكَ أَمْرًا {69}
He (Prophet Musa) said: ‘If Allah so desires it, you will find me patient and I shall not be disobedient to you in any matter’ [18:69]
فقال موسى (عليه السلام): سَتَجِدُنِي إِنْ شاءَ اللَّهُ صابِراً وَ لا أَعْصِي لَكَ أَمْراً قال الخضر (عليه السلام): فَإِنِ اتَّبَعْتَنِي فَلا تَسْئَلْنِي عَنْ شَيْءٍ حَتَّى أُحْدِثَ لَكَ مِنْهُ ذِكْراً يقول: لا تسألني عن شيء أفعله، و لا تنكره علي حتى أخبرك أنا بخبره، قال: نعم
Prophet Musa-as said: He said: ‘If Allah so desires it, you will find me patient, and I shall not be disobedient to you in any matter’ [18:69]. Al-Khizr-as said: ‘So If you were to follow me, then you will not question me about anything until I narrate to you of it with a mention [18:70]’. He-as was saying: ‘Do not question me-as about anything which I-as do, and do not deny it to me-as until I-as inform you-as with its news’. He-as said: ‘Yes’.[1] (An extract)
