Competing to carry the bier
Question

                I notice in many Muslim funerals men rush to carry the bier and push others away. They run in from the back and those at the front move away so that many men can carry the bier. I ask them why they do this and they say the basis for this is that more people can get blessings for carrying the bier. This seems somewhat unusual because it makes it very likely that the body will actually be dropped and sometimes this indeed occurs. Is there any basis for this practice in Islam?
Praise be to Allah. 
          What is narrated in saheeh reports from the Prophet 
          
          (peace and blessings of Allaah be upon him) is that it is Sunnah to 
          follow the funeral. Al-Bukhaari and Muslim narrated in their Saheehs 
          from Abu Hurayrah (may Allaah be pleased with him) that the Prophet 
          
          (peace and blessings of Allaah be upon him) said: “The duties of a Muslim 
          towards his fellow Muslim are five: to return his greeting, visit him 
          when he is sick, follow his funeral, accept invitations and say ‘Yarhamuk-Allaah 
          (May Allaah have mercy on you) when he sneezes).’” 
 
          They also narrated from Abu Hurayrah (may Allaah be pleased 
          with him) that the Prophet 
          
          (peace and blessings of Allaah be upon him) said: “Whoever attends a 
          funeral and prays over the deceased will have one qeeraat (of reward), 
          and whoever attends until the deceased is buried will have two qeeraats.” 
          He was asked, ‘What are these two qeeraats?” He said, “Like two huge 
          mountains.” 
 
          Undoubtedly whoever carries the bier or helps to carry 
          it until the deceased is buried will attain this great reward and more, 
          for even if there were no saheeh hadeeth concerning this matter, the 
          general principles of sharee’ah indicate that carrying the bier of a 
          Muslim is prescribed in Islam, because it involves treating the deceased 
          with kindness. But if that kind treatment will lead to the problem of 
          people pushing and shoving, as mentioned in the question, then warding 
          off that evil takes precedence over trying to do good.  The reward 
          of the one who hopes to gain reward by carrying the bier is not greater than the reward for the one who forsakes it out of consideration towards his Muslim brothers, and not because he is incapable of doing it.
