What is the ruling on charging mobile phones using the mosque's electricity?

Question : After the introduction, the questioner says: Honorable Shaykh, what is the ruling on a person in i'tikaf (spiritual retreat) using a mobile phone inside the Grand Mosque? And what is the ruling on charging it using the electricity of the Haram (sacred precinct)?

Answer : This is a precise question. As for talking on the mobile phone in the Haram, there is nothing wrong with it, just as you would talk to your companion in the Haram who is next to you; you are talking to the person addressing you via the phone just as you address the person next to you. However, this is on the condition that the phone's reception and transmission are not weak to the extent that it requires raising the voice, which would disturb the people. If the transmission and reception are strong and you speak to the person on the phone in a way that does not cause disturbance, there is nothing wrong with it. But there is another source of disturbance in the phone, which is the phone's alert, the alert by ringtone. Therefore, a person should lower the volume of the mobile phone's ringtone as much as possible so as not to disturb the people. Also, it is not appropriate to place the mobile phone in front of the people, in front of the row. The phone should be placed on its back—do you know the back of the phone from its front? Why? Because if they place it on its back, when a call comes in, the phone's light turns on. People nowadays have little khushu' (humility) in them, so you will find the man in front of the phone, while he is talking, looking at the light, directing his eyes to the phone, and neglecting the prayer. Therefore, if you have a mobile phone, either put it in your pocket, or if you wish, put it in front of you, but on its front, not on its back.
As for charging it from the electricity of the Haram, this is a very good and important question. However, it should be directed to the officials in the Haram. Ask the officials in the Haram: "Do you allow me to charge it from the electricity of the Haram, or not?" The answer lies with them.
No, he is asking about using the mobile phone in the Haram. As for the person in i'tikaf, it is well known that it is appropriate for the person in i'tikaf to occupy himself with nearness to Allah, acts of obedience, and worship, and not to talk much, neither on the mobile phone nor otherwise. May Allah reward you.
