[موسى (عليه السلام) :] وَإِنْ شِئْتَ ثَنَّيْتُ بِمُوسى كَلِيمِ اللهِ (صلى الله عليه وآله) إذْ يَقُولُ: ﴿رَبِّ إِنِّي لِمَا أَنزَلْتَ إِلَيَّ مِنْ خَيْرٍ فَقِيرٌ﴾، وَاللهِ، مَا سَأَلَهُ إِلاَّ خُبْزاً يَأْكُلُهُ، لاِنَّهُ كَانَ يَأْكُلُ بَقْلَةَ الاْرْضِ، وَلَقَدْ كَانَتْ خُضْرَةُ الْبَقْلِ تُرَى مِنْ شَفِيفِ صِفَاقِ بَطْنِهِ، لِهُزَالِهِ وَتَشَذُّبِ لَحْمِهِ
[The example of Mūsā (Moses) :] If you want, I will, as a second example, relate to you concerning Mūsā, the Interlocutor of Allāh  when he said: “O Allāh! I need whatever good Thou mayest grant me.” (Qur’ān, 28:24) By Allāh, he asked Him only for bread to eat because he was used to eating the herbs of the earth, and the greenness of the herbs could be seen from the delicate skin of his belly due to his thinness and paucity of his flesh.
