WHAT TO DO DURING I'TIKAF

The Mu'takif should engage himself in lbadat to the best of his ability. Nafl Salat, Tilawat, Durood, Istighfar and permanent Thikr in general should be the Mu'takifs occupations throughout the duration of his I'tikaf.
When the Mu'takif speaks,
he must speak only what is virtue or what is necessary. The Mutakif should not do anything which conflicts with the spirit of I'tikaf. He should guard his heart, mind, ears, eyes and limbs against all evil, thus deriving maximum benefit from his seclusion in the Musjid.
The Mu'takif is the guest of Allah. He should, therefore, be careful of his behaviour in the House of Allah.
