Ruling on praying behind someone who smokes cigarettes and the narghile

 

We have six classes each day, then we pray Zuhr and we have various people who lead us in prayer. Some of them smoke cigarettes, some smoke the narghile (“hubble-bubble”), and some grow their hair long. What is the ruling on these people leading the prayer? Is it permissible to pray behind them?

Praise be to Allaah. 

Yes,
the prayer is valid, but it is better to appoint as your imaam the one
who reads the Qur’aan best, and who has the best understanding of Islam.
That is better, because the Prophet
(peace and blessings of Allaah be upon him) said: “Let the people appoint
as their imaam the one amongst them who reads the Qur’aan best.” (Narrated
by Muslim, no. 673). The meaning
of the one who reads the Qur’aan best is the one who reads it and acts
in accordance with it, because there is nothing good in reading it and
not acting in accordance with it. If the people appoint a person to
be the imaam, and among the congregation there is someone who reads
the Qur’aan better than he does, that is not right, as implied in the
hadeeth.

 Imaam
Ahmad mentioned in his book Risaalat
al-Sunniyah: If a person leads people in prayer and among
them there is someone who is better than him, they will be in a state
of decline. So it is better for you to be led in prayer by the one who
is most pious, who has the best understanding of Islam and who has the
most knowledge of the Qur’aan. But if we suppose that this man who smokes
cigarettes or who shaves his beard or who smokes the narghile or who
grows his hair long comes forward and leads you in prayer, we say: the
prayer is valid, and you do not need to repeat it, because he is Muslim,
but the prayer is imperfect.

 And
Allaah knows best.
