Jamaat Salaah and Imaamat

Appointing a person who trims his beard less than a fist as Imaam

Q: If there is a resident Imaam of a Masjid, who adheres to the Sunnah outwardly and by Mazhab he is a Hanafi and another Imaam from outside who it seems as though trims his beard is a Shafi/Maaliki. The question is that can the Second Imaam who is not the resident Imaam be allowed to lead the Eid Salaah on the basis that the crowd that attends the Eid Gaah is generally Shafi/Maaliki? If not then will the sin of appointing him to lead the Eid Salaah be on the board members? As the resident Imaam had informed them that the sin will be on their shoulder and not his. Is this statement correct?

Qiyum-ul-layl (Tahajud) in congregation in the month of Ramadhaan

Q: During the last 10 days of Ramadan brothers in our Masjid Perform Qiyum-ul-layl (Tahajud) in congregation. Would like to know if this is permissible, if not then what should we do if you are doing Itikhaff in the masjid. One scholar told has that Deoband has given a special permission to perform Tahajud in Congregation during the last 10 days of Ramadan.
