[Machine] "If you are behind the imam, do not perform the rukoo' (bowing) until he bows, and do not prostrate until he prostrates, and do not raise your head before him. If the imam finishes the prayer, without standing up or turning away and you have a need, then leave and abandon it, as your prayer is completed."
«إِذَا كُنْتَ خَلْفَ الْإِمَامِ فَلَا تَرْكَعْ حَتَّى يَرْكَعَ وَلَا تَسْجُدْ حَتَّى يَسْجُدَ وَلَا تَرْفَعْ رَأْسَكَ قَبْلَهُ فَإِذَا فَرَغَ الْإِمَامُ وَلَمْ يَقُمْ وَلَمْ يَنْحَرِفْ وَكَانَتْ لَكَ حَاجَةٌ فَاذْهَبْ وَدَعْهُ فَقَدْ تَمَّتْ صَلَاتُكَ»
