Sahih al-Bukhari · Book 63: Merits of the Helpers in Madinah (Ansaar) · The emigration of the Prophet (saws) to Al-Madina
Narrated 'Ata bin Abi Rabah:
وَحَدَّثَنِي الأَوْزَاعِيُّ ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ ، قَالَ زُرْتُ عَائِشَةَ مَعَ عُبَيْدِ بْنِ عُمَيْرٍ اللَّيْثِيِّ فَسَأَلْنَاهَا عَنِ الْهِجْرَةِ، فَقَالَتْ لاَ هِجْرَةَ الْيَوْمَ، كَانَ الْمُؤْمِنُونَ يَفِرُّ أَحَدُهُمْ بِدِينِهِ إِلَى اللَّهِ تَعَالَى وَإِلَى رَسُولِهِ صلى الله عليه وسلم مَخَافَةَ أَنْ يُفْتَنَ عَلَيْهِ، فَأَمَّا الْيَوْمَ فَقَدْ أَظْهَرَ اللَّهُ الإِسْلاَمَ، وَالْيَوْمَ يَعْبُدُ رَبَّهُ حَيْثُ شَاءَ، وَلَكِنْ جِهَادٌ وَنِيَّةٌ.
`Ubaid bin `Umar Al-Laithi and I visited Aisha and asked her about the Hijra (i.e. migration), and she said, "Today there is no (Hijrah) emigration. A believer used to run away with his religion to Allah and His Apostle lest he should be put to trial because of his religion. Today Allah has made Islam triumphant, and today a believer can worship his Lord wherever he likes. But the deeds that are still rewardable (in place of emigration) are Jihad and good intentions." (See Hadith No. 42 Vol. 4).
