Shaykh Sulaymân al-‘Alwân فك الله أسره was asked: What is the ruling on abandoning Suhûr?
He answered: Abandoning Suhûr is an imitation of Ahlul-Kitâb, and some of the people are lenient regarding the matter of Suhûr, claiming that they do not desire it. It is a priority for the Muslim that he does not miss Suhûr, even by drinking a sip of milk to differ from Ahlul-Kitâb, and to follow the Sunnah of the Prophet ﷺ.
It has come in the report from ‘Amr ibn al-‘Âs that the Prophet ﷺ said: “The difference between our fasting and the fasting of Ahlul-Kitâb is eating shortly before Fajr.” Narrated by Imâm Muslim.
This is indicates that [having] Suhûr is a differentiation from Ahlul-Kitâb, and differing from them is a very [important] aim in the Sharî’ah.
