About prayers

I guess one could distinguish between acceptable prayers and unacceptable prayers as one would do between acceptable bribery and unacceptable bribery.

Here prayer is for the future gains or thanking the deity for any gains.

Acceptable:
1. sickness
2. fertility
3. impending fatal danger
4. clearing an exam

Unacceptable:
1. surviving an accident in which many others perished
2. for jobs
3. for better grades
4. more money

Basically, anything where the believer is the only beneficiary is acceptable, however, in situations where it appears as if god/s has/ve to take sides praying is unacceptable. One shouldn't put limits on gods for the greater good of the society.
