Offer Your Seat to Somebody Else

If there is shortage of seats during a bus or train journey, those people sitting should not remain sitting and those people standing should not remain standing for the whole journey. Everyone should take turns to sit and thus earn reward of facing a difficulty. Sayyiduna Abdullah bin Mas’ood  radi allahu anhu says that there was only one camel for three persons in the battle of Badr, hence, Sayyiduna Abu Lubaba and Sayyiduna The Respect of a Muslim Ali radi allahu anhu were with the camel of the Holy Prophet sallallahu alaihi wasallam  Both say that when it was the turn of the Prophet  sallallahu alaihi wasallam to walk, both of us would request the Prophet  sallallahu alaihi wasallam to remain seated and that we will walk in lieu of him. The Holy Prophet sallallahu alaihi wasallam replied, “You are not stronger than me and I am not indifferent to reward.” (i.e. I also need reward so why should I not walk!)
