I found these words...

Istawoo (استووا): Straighten up

Tarassoo (تراصوا): pack up

Sawwoo Sufoofakum (سووا صفوفكم): Straighten your rows

I'tadiloo (اعتدلوا): Up right

Suddul Khalal (سدوا الخلل): bridge the gaps

I apologize for the confusion. The phrases you mentioned are indeed commonly used by the imam or prayer leader before the start of the congregational prayer. They are instructions given to the worshippers to ensure that the rows are straight and properly aligned. These instructions are meant to create an atmosphere of unity and focus during the prayer. The phrases you provided can be translated as follows:

1. Istawoo (استووا): Straighten up

2. Tarassoo (تراصوا): Pack up

3. Sawwoo Sufoofakum (سووا صفوفكم): Straighten your rows

4. I'tadiloo (اعتدلوا): Upright

5. Suddul Khalal (سدوا الخلل): Bridge the gaps

By following these instructions, the worshippers ensure that they stand shoulder to shoulder and eliminate any gaps or uneven lines between them. This practice symbolizes unity and equality before Allah during the congregational prayer.
