Is it permissible to recite the invocations of ruku and sajdah one time which we normally recite three times?
Dear Brother / Sister,
It is fard to wait in ruku and sajdah long enough to say "subhana rabbiyal azim" (Glory be to my Lord Almighty) or "subhana rabbiyal a'la" (Glory be to my Lord, the Most High). It is sunnah to say three times "subhana rabbiyal azim" in ruku and "subhana rabbiyal a'la" in sajdah. This is the minimum number of invocations that are said in ruku and sajdah. It is mustahab (recommended) to increase this number to five or seven as long as it is odd. However, the imam should not do this more than three times. (al-Hidaya - al-Muhit / Sarakhsi)
The Islamic canonist experts say that the minimum number of invocations is three, the average of it is five and the perfect of it is seven.
It is also permissible to recite the invocations of ruku and sajdah one time. By this way, the fard is fulfilled.
Questions on Islam
- Does sajda as-sahw (prostration of forgetfulness) become necessary if we change the places of the invocations that we recite in ruku and sajdah?
- What is the criterion for the length of the ruku and sajdah in prayers? How many times can invocations be recited at ruku (bowing down in prayer) and sajdah (prostration) at most?
- What is the place of ruku (bowing down in prayer) in salah? What meaning does it have and are there any verses or hadiths about it?
- What is the criterion for dua (supplication) in prostration? Is it permissible to pray for something worldly in prostration or to say something other than "subhana rabbiyal a'la"? Is prayer invalidated if something else is said?
- What is the length of sajdah (prostration) in prayer? They say it is necessary to remain in prostration long enough to say, "Lailahaillallah"; I sometimes think I do not remain long enough.
- How is tasbih prayer performed?
- Is it permissible to say “Subhana Rabbiyal a’la” (Glory to my Lord, the Most High) more than three times in sajdah (prostration) while praying?
- I am trying to understand the Prophet’s (pbuh) performing his prayers long. He can lengthen qira’ah after al-Fatiha but how can a prostration be lengthened? Saying "Subhana Rabbiyal ala" three times does not take very long; is it possible to say it more?
- Are the duas (supplications) said in ruku’ (bowing down) and sajdah (prostration) of prayer fard?
- How long should the chapters to be read in congregational prayers be? Is it permissible to read long chapters?
