عَنْ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”إِذْنُكَ عَلَيَّ أَنْ تَرْفَعَ الْحِجَابَ وَأَنْ تَسْتَمِعَ سِوَادِي حَتَّى أَنْهَاكَ“ قَالَ أَبُو عَبْدِ الرَّحْمَنِ قَالَ أَبِي بِسَوَادِي سِرِّي قَالَ أَذِنَ لَهُ أَنْ يَسْمَعَ سِرَّهُ
Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: The lifting of the curtain is equivalent to granting you permission to come forward, and you are also authorized to listen to my confidential matters, until I prevent you from it. Abu Abdur Rahman said: The meaning of "Siwad" is secrets, that is, the Prophet (peace and blessings be upon him) had given them permission to listen to confidential matters.
