عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَمَّا قَالَ فِرْعَوْنُ {آمَنْتُ أَنَّهُ لَا إِلَهَ إِلَّا الَّذِي آمَنَتْ بِهِ بَنُو إِسْرَائِيلَ} [يونس: 90] قَالَ قَالَ لِي جِبْرِيلُ يَا مُحَمَّدُ لَوْ رَأَيْتَنِي وَقَدْ أَخَذْتُ حَالًا مِنْ حَالِ الْبَحْرِ فَدَسَسْتُهُ فِي فِيهِ مَخَافَةَ أَنْ تَنَالَهُ الرَّحْمَةُ
Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: When Pharaoh said: {آمَنْتُ أَ نَّہُ لَا اِلٰہَ إِلَّا الَّذِی آمَنَتْ بِہِ بَنُو إِسْرَائِیلَ} … I believe that there is no true deity except the One in whom the Children of Israel believe. Then Jibreel (peace be upon him) said to me: O Muhammad! If only you could have seen me at that time when I was taking the black mud of the sea and stuffing it into Pharaoh’s mouth, fearing that (Allah’s) mercy might reach him.
(وَعَنْهُ مِنْ طَرِيقٍ ثَانٍ) عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ إِنَّ جِبْرِيلَ كَانَ يَدُسُّ فِي فَمِ فِرْعَوْنَ الطِّينَ مَخَافَةَ أَنْ يَقُولَ لَا إِلَهَ إِلَّا اللَّهُ
(Second chain) The Noble Prophet (peace and blessings be upon him and his family) said: Jibreel (peace be upon him) was stuffing clay into Pharaoh’s mouth out of fear that he might say LAA ILAAHA ILLALLAH.
