What is the ruling on keeping pictures that gather me with my sisters and paternal aunts if they refuse to give them to me, and what is the ruling on keeping pictures on a mobile phone?

It is not permissible to keep pictures of living beings for remembrance. The Shar'i ruling must be clarified to those who keep them, and they should be advised to dispose of them. As for digital images on mobile phones and computers, and what is recorded on video, they do not take the ruling of photographic images due to their impermanence. Therefore, there is no harm in keeping them as long as they do not contain anything prohibited.
