Is there any limit in reading tasbih of sajda(subhana rabbiyal ala) and tasbih of ruku(subhana rabbiya al azeem) or it may be read any number of times like 11,13,19 etc? Also ,is it necessary to say tasbih odd number of times?
We learn from hadith that reading tashib thrice in ruku and sajdah is good, five times is better while reading seven times is the best. However, if one offers long nafl salah he may read 9, 11, 13 and 15 times. There is no limit, but it should be noted that reciting tasbih in odd numbers is better.
Allah (Subhana Wa Ta’ala) knows Best
