It is reported from Ibn Sīrīn – Allāh have mercy on him – that a man once said to Ibn ‘Umar – Allāh be pleased with him:
Can we offer you some Jawārish? He inquired, “And what is Jawārish?” The man replied, “It is something that will help you digest your food if you get too full up.” Ibn ‘Umar said, “I have not eaten my fill for four months – not because I cannot find food, but because I have lived with people who used to eat their fill at times and go hungry at others.
Abū Dāwūd, Al-Zuhd article 325.
It is reported that Al-Hasan Al-Basrī – Allāh have mercy on him – said:
By He in whose Hand is my soul, I have lived amongst people who never ordered food to be prepared for themselves If [food] was presented to one of them, he would eat, otherwise, he would be silent; and he would not care if it was hot or cold.
Abū Nu’aym, Hilyatu Al-Awliyā` 6:270.
It is also reported that he said:
By Allāh, I have lived amongst people who when taking lunch, if they were about to be full, would stop eating.

A man from the Companions of the Prophet – praise and peace of Allāh be upon him – would sometimes go three days without finding anything to eat, so he would grill some animal skin and eat that. If he couldn’t find anything at all, he would [tie] a rock to himself to straighten his back.
Ibid. article 61.
