What is the ruling on using a mobile phone for one who is in i'tikaf (spiritual retreat in the mosque)?

The questioner : May Allah reward you. The questioner asks: What is the ruling on using a mobile phone for the one who is in i'tikaf?

The Shaykh : There is nothing wrong with it, but on the condition that it is only when there is a need. This is because the sunnah (recommended practice) for the one in i'tikaf is to devote himself to worship, not to idle talk that has no benefit. So if the need of the one in i'tikaf calls for him to call his family, there is nothing wrong with it. But what do you say if the one in i'tikaf calls merchants and says, "I will buy from you such-and-such goods for such-and-such, and I will sell you such-and-such goods for such-and-such"? The ruling is that his i'tikaf is invalidated.
Because buying and selling by the one in i'tikaf invalidates the i'tikaf, whether he does it in the mosque or outside the mosque. And if he does it in the mosque, the sin is greater, for the Prophet (peace and blessings be upon him) said: For the mosques were not built for this.

The presenter : May Allah reward you. A woman entered the state of ihram (the consecrated state of pilgrimage) from the miqat (the boundary at which ihram is entered)?

The Shaykh : This one says that the one who talks on the mobile phone charges the battery from the electricity of the Haram (the sacred precinct). We say this is a behavior; the electricity of the Haram was not provided for this, but rather for the benefit of the Haram. And this is a private matter for the owner of the mobile phone. So we tell him: if the battery runs out in this answer, that is it; when the i'tikaf ends, he will charge it at his home. Yes.
