the believers are those who believe in god and his messenger and when they are with him for a matter of common interest they do not leave until they have asked him for permission. those who ask your permission are those who believe in god and his messenger. so when they ask your permission to attend to some affair of theirs give permission to any of them you wish and ask gods forgiveness for them. god is forgiving and merciful.
إنما المؤمنون الذين آمنوا بالله ورسوله وإذا كانوا معه على أمر جامع لم يذهبوا حتى يستأذنوه إن الذين يستأذنونك أولئك الذين يؤمنون بالله ورسوله فإذا استأذنوك لبعض شأنهم فأذن لمن شئت منهم واستغفر لهم الله إن الله غفور رحيم
