'Amr ibn Shu'ayb reported via his father that his grandfather, "The Prophet, may Allah bless him and grant him peace, sat down on the steps of the Ka'ba in the year of Conquest* and praised and glorified Allah. Then he said, 'Whoever is party to an alliance made in the Jahiliyya, Islam only increases its strength. There is no hijra after the Conquest.'"  

عَنْ جَدِّهِ قَالَ جَلَسَ النَّبِيُّ ﷺ عَامَ الْفَتْحِ عَلَى دَرَجِ الْكَعْبَةِ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ مَنْ كَانَ لَهُ حِلْفٌ فِي الْجَاهِلِيَّةِ لَمْ يَزِدْهُ الإِسْلاَمُ إِلاَّ شِدَّةً وَلاَ هِجْرَةَ بَعْدَ الْفَتْحِ
