Re: Muslims can not follow Prophet's life
The list of things include those things that we can follow but will render us incapable of keeping balance with our other duties.
Often the things that are forbidden for us are forbidden because a Sahabi would emulate it in RasoolAllah (SAW) but would then get told not to do it and be given the reason why ... The nature of RasoolAllah (SAW) would be to always give light things for his companions to do and when they asked for more he (SAW) would add slowly to them ...
Amount of prayer - Agree. I think there were certain nawafil that were obligatory for him. In Surah e Muzammil, certain relaxations announced.
**
Number of wives - **Agree. There were certain exemptions only available to the Prophet, but we can at least try to follow the equality and justice in case of more than one wife.
Fasting duration and number of days - *30 days of Ramadan and 3 days a month are enough for Muslims. Many Sahaba and Tabiyeen followed alternate day fasting. *
Receiving revelation - No doubt about it and there is no need for 'follow' aspect in this, as we believe wahi's chapter is closed on him.
Level of consciousness of Allah (SWT) (taqwa) - Obviously, but there are things that we can follow (not to that level). Like we are accountable to God for all of our actions. When Prophet was so conscious about fear of God, then we should be more careful and not take our lives and actions for granted to invite God's wrath.
To be sinless : This is the attribute for Prophets only. We can't claim for such purity, so I don't think there is 'follow' aspect, except we should try to save ourselves from sins as per guidance provided by the Prophet.
Patience: God is with 'Saabreen'. The plural says that Sabr was just not for the Prophet, but necessary to follow for others. We can't reach that level obviously. BTW, current meaning of Sabr is perplexed. Just submit to atrocities is also Sabr in today's world, but Islam and Prophet doesn't advocate such type of Sabr.
Charity - Sayyiduna Abu Bakr (RA) did give everything, but Sayyiduna RasoolAllah (SAW) returned back to us from Jannah !!! Interesting thought, but except for level and extent of charity, people did follow teachings of the Prophet regarding Charity, **as you name Hazrat Abu Bakr (RA)***.*
The Ascension itself : Please explain
Prophecy : Obvious. Its limited to Prophets and not for followers.
Ability to kill Dajjal : Special attribute / power given by God. There is nothing for striving to follow here. May be , it teaches us that when it comes to 'Haq', don't see the power of person who is going against Haq.
