إِذَا دَخَلْتَ الْمَسْجِدَ وَ الْإِمَامُ رَاكِعٌ فَظَنَنْتَ أَنَّكَ إِنْ مَشَيْتَ إِلَيْهِ يَرْفَعُ رَأْسَهُ مِنْ قَبْلِ أَنْ تُدْرِكَهُ فَكَبِّرْ وَ ارْكَعْ وَ إِذَا رَفَعَ رَأْسَهُ فَاسْجُدْ مَكَانَكَ فَإِنْ قَامَ فَالْحَقْ بِالصَّفِّ وَ إِنْ جَلَسَ فَاجْلِسْ مَكَانَكَ فَإِذَا قَامَ فَالْحَقْ بِالصَّفِّ .
Translation
Muhammad Bin Yahya, from Abdullah Bin Muhammad Bin Isa, from Ali Bin Al Hakam, from Aban, from Abdul Rahman Bin Abu Abdullah, (It has been narrated) from Abu Abdullah<sup>asws</sup> having said: ‘Whenever you enter the Masjid and the Imam is in <span class="iTxt">Rukū</span>, so you think that if you were to walk over to him, he would raise his head before you reach, exclaim a Takbīr and go into Rukū. And when he does raise his head, so perform Sajdah in your place. So if he were to stand, so join up with the row, and if he was seated, so sit in your place. So when he stands, then join up with the row’.
