Q. During Salaah, if one falls into deep thoughts and delays performing the next posture of Salaah, but continues performing the Salaah, is the Salaah still valid?
A. If a person delays the performance of a posture of Salaah due to falling into deep thoughts for the duration in takes to recite the 3 Tasbeehs in Ruku’ or Sajdah (approximately 5 seconds), it will necessitate the performance of a Sajdah Sahw to compensate for it.
If the delay is less than this duration of time, the performance of a Sajdah Sahw will not be necessary and the Salaah will remain valid. (Tahtaawi Ala Maraaqil Falaah 1/474)
