if the majority of those aboard a ship, apart from few, want to shorten and combine prayers for reasons like saving water, should those few persons follow the majority
to get the reward and keep the unity? If the majority (Part No. 8; Page No. 103) do not want to perform Sawm (Fast), should the minority comply with them?
If the case is as you mentioned, then it is better for the minority to agree with the majority of travelers to preserve unity and save water.As for not observing Sawm while on a journey, it is better for the entire group not to fast during travel. Nonetheless, whoever wishes to fast, there is nothing wrong with that, regardless of the opinion of the majority or the minority. There is evidence in the authentic Sunnah of the Messenger of Allah (peace be upon him) in this regard.
