Ibn Mas'ud said:
حَدَّثَنِي يُونُسُ بْنُ عَبْدِ الأَعْلَى الصَّدَفِيُّ ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ ، أَخْبَرَنِي عَمْرُو، بْنُ الْحَارِثِ عَنْ سَعِيدِ بْنِ أَبِي هِلاَلٍ ، عَنْ عَوْنِ بْنِ عَبْدِ اللَّهِ ، عَنْ أَبِيهِ ، أَنَّ ابْنَ مَسْعُودٍ ، قَالَ مَا كَانَ بَيْنَ إِسْلاَمِنَا وَبَيْنَ أَنْ عَاتَبَنَا اللَّهُ بِهَذِهِ الآيَةِ { أَلَمْ يَأْنِ لِلَّذِينَ آمَنُوا أَنْ تَخْشَعَ قُلُوبُهُمْ لِذِكْرِ اللَّهِ} إِلاَّ أَرْبَعُ سِنِينَ .
Since our acceptance of Islam and the revelation of this verse in which Allah has shown annoyance to us:" Has not the time yet come for the believers that their hearts should be humble for the remembrance of Allah?" (lvii. 16), there was a gap of four years.
