Ramadan is a month of giving and sharing. Giving gifts is highly recommended.
Narrated Abu Huraira that the Prophet, Sallallaahu alayhi wa sallam, said, “I shall accept the invitation even if I were invited to a meal of a sheep’s trotter, and I shall accept the gift even if it were an arm or a trotter of a sheep.”
Sahih Al Bukhari, Volume 3, No 742
Narrated ‘Aisha that Allah’s Apostles, Sallallaahu alayhi wa sallam, used to accept gifts and used to give something in return.
Sahih Al Bukhari, Volume 3, No 758
Please note however.
Narrated Abu Umamah: The Prophet, Sallallaahu alayhi wa sallam, said: If anyone intercedes for his brother and his brother presents a gift to him for it, and he accepts it, he approaches a great door of the doors of usury.
