Don’t join the army or serve jury duty
“As for serving in the army, I would personally advise Muslims not to join the army of a non-Muslim-majority country. The reason behind this advice is that they may be forced to fight and kill other Muslims, which is clearly prohibited.”
“It is no secret to anyone that the reference point for passing judgement on people in the country asked about and — unfortunately — in many Muslim countries is not the Qur’aan and Sunnah. Based on that, the starting point for passing judgement on people — both Muslims and kaafirs — is man-made laws, which are opposed to the laws of the Lord of the Worlds. Based on that, it is not permissible to serve on the jury or work in any other part of the courts which judge between people on the basis of something other than that which Allaah has prescribed.”
Now as for that Jinni in your house…
74. The groom’s supplication on the wedding night or when buying an animal
when you marry a woman or buy a maidservant, you should say:
اللّهُـمَّ إِنَّـي أَسْـأَلُـكَ خَيْـرَها، وَخَيْـرَ ما جَبَلْـتَهـا عَلَـيْه، وَأَعـوذُ بِكَ مِنْ شَـرِّها، وَشَـرِّ ما جَبَلْـتَهـا عَلَـيْه.
Allahumma innee as-aluka khayraha wakhayra ma jabaltaha AAalayh, wa-aAAoothu bika min sharriha washarri ma jabaltaha AAalayh.
‘O Allah, I ask You for the goodness within her and the goodness that you have made her inclined towards, and I take refuge with You from the evil within her and the evil that you have made her inclined towards.’
…and if you buy a camel, then you should take hold of it’s hump and say likewise.’
