3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sa‘id al-A’raj who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who comes to Salah (prayer) and does not find a place in the rows. Can he stand up alone until Salah (prayer) is complete? He (the Imam) said, ‘Yes, it is not an offense to stand parallel to the Imam.’”

4. Ali ibn Ibrahim has narrated from his father from Hammad ibn ‘Isa from Hariz from Zurarah who has said the following: “Abu Ja‘far (a.s.), has said, ‘If a people perform Salah (prayer) and there is a space between them and the Imam, which cannot be covered by one step, that Imam is not their Imam. Any row which performs Salah (prayer) following an Imam and the space between this and the row in front is more than can be covered by one step it is not of that (row). If there is a barrier or wall in between, it is not a Salah (prayer) for them unless one is in front of a door.’ He (the narrator) has said that he (the Imam) said, ‘These arches did not exist in the time of anyone. The tyrants have invented them. Salah (prayer) of those who perform behind them, following those who perform inside is not valid Salah (prayer).’ Abu Ja‘far (a.s.), has said, ‘The rows must be complete, connected with each other and there must be a space of one step between two rows. The space must be of the length of human body that falls (when in Sajdah (prostration)).”’

5. Muhammad ibn Yahya has narrated from ‘Abd Allah ibn Muhammad ibn ‘Isa from Ali ibn al-Hakam from Aban from ‘Abd al- Rahman ibn abu ‘Abd Allah who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘When you enter a Masjid and the Imam is in Ruku‘ (bowing down on one’s knees) and you think that if you walked all the way to join, he raises his head before you join. Say Takbir (Allah is great beyond description) perform Ruku‘, and if he raised his head, perform Sajdah (prostration) where you are, and if he stood up, join the row, and if he sits down sit down in your place, and when he stands up, join the row.’”
