Ibn 'Abbas (May Allah be pleased with them) reported:
Messenger of Allah ﷺ went to bed hungry for several successive nights, nor did his family have a thing for supper for many consecutive nights; and their bread was mostly of barley.

[At- Tirmidhi].

وعن ابن عباس رضي الله عنهما قال : كان رسول الله ﷺ يبيت الليالي المتتابعه طاويا، وأهله لايجدون عشاء ، وكان أكثر خبزهم خبز الشعير . ((رواه الترمذي وقال : حديث حسن صحيح)).
