Sahih Bukhari Volume 5, Book 64, Hadith 4314

حَدَّثَنَا إِسْحَاقُ بْنُ يَزِيدَ، حَدَّثَنَا يَحْيَى بْنُ حَمْزَةَ، قَالَ حَدَّثَنِي الأَوْزَاعِيُّ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ، قَالَ زُرْتُ عَائِشَةَ مَعَ عُبَيْدِ بْنِ عُمَيْرٍ فَسَأَلَهَا عَنِ الْهِجْرَةِ، فَقَالَتْ لاَ هِجْرَةَ الْيَوْمَ، كَانَ الْمُؤْمِنُ يَفِرُّ أَحَدُهُمْ بِدِينِهِ إِلَى اللَّهِ وَإِلَى رَسُولِهِ صلى الله عليه وسلم مَخَافَةَ أَنْ يُفْتَنَ عَلَيْهِ، فَأَمَّا الْيَوْمَ فَقَدْ أَظْهَرَ اللَّهُ الإِسْلاَمَ، فَالْمُؤْمِنُ يَعْبُدُ رَبَّهُ حَيْثُ شَاءَ، وَلَكِنْ جِهَادٌ وَنِيَّةٌ‏.‏

Narrated By 'Ata' bin Abi Rabah : 'Ubaid bin 'Umar and I visited 'Aisha, and he asked her about the migration. She said, "There is no migration today. A believer used to flee with his religion to Allah and His Prophet for fear that he might be put to trial as regards his religion. Today Allah has rendered Islam victorious; therefore a believing one can worship one's Lord wherever one wishes. But there is Jihad (for Allah's Cause) and intentions."
