Shaykh ul-Islaam Ibn Taymiyyah [رحمه الله] said:

❝Helping the poor with food in the month of Ramadan is from the Sunnan [practice] of Islaam.

Indeed the Prophet [ﷺ] said: ‘Whoever opens the fast of a person fasting then he gets the like of his reward.’❞

[Al-Fatawa, (25/298) | Translated By Abbas Abu Yahya Miraath Al-Anbiyya]
