In his collection of various reflections on the Qur’an that he penned during Ramadan, Sheikh ‘Abd al-Rahman al-Sa’di included a beautiful section on some of the du’a found within the Qur’an. What follows is his explanation of the du’a of Yusuf after being reunited with his family:
وكذلك: دعاء يوسف عليه السلام: ﴿رَبِّ قَدْ آتَيْتَنِي مِنَ الْمُلْكِ وَعَلَّمْتَنِي مِنْ تَأْوِيلِ الْأَحَادِيثِ فَاطِرَ السَّمَاوَاتِ وَالْأَرْضِ أَنْتَ وَلِيِّي فِي الدُّنْيَا وَالْآخِرَةِ تَوَفَّنِي مُسْلِمًا وَأَلْحِقْنِي بِالصَّالِحِينَ﴾[يوسف: 101] فتوسل إلى الله بربوبيته وبنعمة الله عليه بنعمة الدنيا وهي: الملك وتوابعه، ونعمة الدين وهي: العلم الكامل، وبولاية الله وانقطاعه عن غيره، وتولي الله له في الدنيا والآخرة: أن يثبته على الإسلام الظاهر والباطن حتى يلقاه عليه، فيدخله في خُلص عباده الصالحين. ـ
Another example of a comprehensive du’a is the du’a of Yusuf:
رَبِّ قَدْ آتَيْتَنِي مِنَ الْمُلْكِ وَعَلَّمْتَنِي مِن تَأْوِيلِ الْأَحَادِيثِ ۚ فَاطِرَ السَّمَاوَاتِ وَالْأَرْضِ أَنتَ وَلِيِّي فِي الدُّنْيَا وَالْآخِرَةِ ۖ تَوَفَّنِي مُسْلِمًا وَأَلْحِقْنِي بِالصَّالِحِينَ
Lord, You have given more some ownership and taught me some interpretation of events. Originator of the heavens and the earth, You are my Protector in this life and the next. Cause me to die as a Muslim and join me with the righteous. [12:101]
So he was calling on Allah by His Lordship and the by the favors that Allah had granted him:
a worldly blessing: ownership and what comes with it
and a spiritual blessing: complete knowledge
and by how he has taken Allah as his protector and turned away from any others besides Him.
