وَقَالَ حَبِيبُ بْنُ أَبِي عَمْرَةَ ، عَنْ سَعِيدٍ ، عَنْ ابْنِ عَبَّاسٍ ، قَالَ: قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِلْمِقْدَادِ: "إِذَا كَانَ رَجُلٌ مُؤْمِنٌ يُخْفِي إِيمَانَهُ، مَعَ قَوْمٍ كُفَّارٍ، فَأَظْهَرَ إِيمَانَهُ، فَقَتَلْتَهُ، فَكَذَلِكَ كُنْتَ أَنْتَ تُخْفِي إِيمَانَكَ بِمَكَّةَ مِنْ قَبْلُ".
صحیح بخاری · Hadith 6866
The Prophet also said to Al-Miqdad, "If a faithful believer conceals his faith (Islam) from the disbelievers, and then when he declares his Islam, you kill him, (you will be sinful). Remember that you were also concealing your faith (Islam) at Mecca before."
