Taking a vow not to use Facebook and thereafter mistakenly opening someone else's Facebook
Q: One day my wife made a vow to Allah that she will never use Facebook in the future. Her sister uses facebook and always has automatic login into facebook on her mobile. When my wife uses her sisters mobile, mistakenly she opened the facebook app and automatic logged into her sisters facebook account or profile. She saw her sisters Facebook profile picture etc. but she didn't use Facebook, she just saw it.
