Start fasting on seeing the cresent of Ramdan & give up fasting on seeing the cresent of Shawwal .

The Prophet Muhammad ﷺ taught us that when we see the crescent of Ramadan, we should begin our fast. We should continue our fast until we see the crescent of Shawwal. If it is cloudy and we cannot see either crescents, then we should complete thirty days in Sha’ban. This teaches us that it is important to be mindful about when to start and end our fast during Ramadan so that it can be done properly according to Islamic teachings. It also teaches us that even if there are obstacles in our way such as clouds blocking out view, then still have faith in Allah SWT and follow His instructions as best as possible.
