Faṭimah: If someone is obligated to perform ghusl but deliberately or out of embarrassment fails to do so, is this a sin?

Mother: Being embarrassed is not a valid excuse to skip an obligatory ghusl unless it entails unbearable difficulty. If someone delays ghusl without a valid reason until the time for prayer (including ghusl) becomes short, he has sinned. However, if the time is very short, the obligation shifts from ghusl to tayammum (dry ablution), meaning he must pray with tayammum and then perform ghusl for future prayers.

Faṭimah: Is this same ruling applicable to fasting in Ramaḍān?

Mother: Yes, if a woman becomes pure during the night, she must perform ghusl before the call to Dawn prayer (Fajr) and fast. If she deliberately does not perform ghusl and the time becomes tight, she has sinned and must perform tayammum before dawn, and her fast will be valid. However, she must perform ghusl to perform the Dawn prayer.
