Salaah

Making a second jamaat in the masjid

Q: I have read a few times that men should not join the second and third jamaats in the Masjid. 

In the UK, many of the Masajid are very small, serving a large number or Muslims. However, in recent years they have introduced second and third jamaats to avoid people praying on the pavement which is used by everyone public. 

Is it still the case that instead of joining the second jamaat, men should pray alone in the Masjid?

Repelling the evil whispers of shaitaan in salaaah

Q: Is it permissible/recommended for a person to spit in salaah if he finds whispers of shaitaan troubling him? Is there anything else he should rather do based on authentic narrations? 

The below narration is from Muslim Shareef: 

O Messenger of Allah, the shaytaan interferes between me and my prayer and my recitation, and he makes me confused. The Messenger of Allah (blessings and peace of Allah be upon him) said: “That is a devil called Khinzab. If you feel that, then seek refuge with Allah from him and spit dryly to your left three times.” He said: I did that and Allah took him away from me. 

Please advise.
