Is it obligatory to place the foot against the foot in straightening the rows?

Question:
Honorable Shaykh, the questioner asks: Is placing the foot against the foot on one’s side part of straightening the rows? Because some people feel uncomfortable when placing their foot against another’s foot?

Answer:
It is not permissible for you to cause discomfort to the person next to you by saying, “I refuse to place my foot against his foot.” Placing the foot against the foot is not prescribed; what is prescribed is alignment, such that there is no gap through which Satan can enter. However, a slight gap that is unavoidable between two standing people is not tolerated. Some brothers spread their legs, taking up the space of two feet, in order to center the person next to him and the person next to that one, taking up the space of two feet with his own feet and causing discomfort to both of them. This is not permissible, it is not prescribed, and it is an act of excessive effort. Yes.
