Musical Tunes on cell phones:
It is not permissible to use the musical tunes on telephones or any other kind of gadget, because listening to musical instruments is haraam as is indicated by the evidence of sharee3ah. We should do without them and use the regular ringing.(1)
The Standing Committee for Issuing Fatwas was asked about the ruling on musical tunes on mobile phones. They replied:
It is not permissible to use musical tunes for telephones or any other devices, because listening to musical instruments is haraam, as is indicated by the evidence of sharee3ah. It is possible to do without them by using the ordinary ringing tone. And Allaah is the Source of strength. (2)
Using Adhaan, Qur’aan verses or Recitation of Qur’an as Mobile ring tones:
Shaykh Saalih al-Fawzaan said:
This is degrading (or misusing) the Adhaan, Thikr, and the Noble Qur’aan. So these should not be taken as alarms (i.e. ring tones). The Qur’aan is not to be taken for use as an alarm. It might be said: “This is better than music!” Ok, the music – are you forced to use it?!
Leave the music, and put something that is an alarm tone (i.e. normal ringing). Something that does not contain music, nor does it contain Qur’aan. It should be a simple ring only. (3)
The Islamic Jurisprudence Council has banned the use of the verses of the Qur’aan as ringtones for mobile phones because it impinges on the sacred character of the the Book.
“It is demeaning and degrading to the verses of the Holy Book to stop abruptly at the middle of a recitation or neglecting the recitation, as happens when they are used as ringtones in mobile phones.” (4)
Ringing of mobile phones in the mosques:
Shaykh Muhammed Salih Al-Munajjid said:
Setting mobile phones to ring with a musical tone is reprehensible and haraam, and it is even worse and more haraam if that happens in the houses of Allaah, namely the mosques, because that is openly committing falsehood and haraam in that place, so the sin of the one who brings it with him is even worse in the mosque.
It is known that the Prophet sallAllaahu 3Alayhi wa sallam stated that musical instruments are haraam, meaning the instruments that give these musical sounds. These mobile phones have these sounds recorded in them which is repeated every time a call comes to the owner of the phone. I wonder what will be recorded in the record of deeds of those who make their mobile phones play music in the houses of Allaah during the prayer, and disturb themselves and others, and make the voice of falsehood and the musical instruments of the Shaytaan echo loudly in the houses of Allaah.
Do they not fear their Lord and repent to Him and give up what they are doing and change this evil, especially when there is a permissible alternative in the other regular, non-musical sounds that they can choose for the phone’s ring?
We should note that the ringing of the telephone, even if it is a permissible sound, should still be turned off before entering the mosque, so that it will not disturb the worshippers. (5)
