رَبِّ إِنِّي لِمَا أَنزَلْتَ إِلَيَّ مِنْ خَيْرٍ فَقِيرٌ
Rabbi ‘inni limaa ‘anzalta ‘ilayya min khairin-faqeer
O my Lord! I am indeed needy of whatever good You may send to me
[Surah Qassas; 28:24]
The above du’a was made whilst sayyidina Musa (alayhis salam) was traveling to the desert of Madyan, with no place of shelter. He made this du’a while resting under the shade of a tree.
