Dosa yang paling besar di sisi Allah menyekutukan Allah, membunuh anakmu karena takut membuat kelaparan, berzina dengan istri tetanggamu
Imam Ahmad : 5189
حَدَّثَنَا عَفَّانُ حَدَّثَنَا أَبُو عَوَانَةَ حَدَّثَنَا يَزِيدُ بْنُ أَبِي زِيَادٍ عَنْ مُجَاهِدٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَا مِنْ أَيَّامٍ أَعْظَمُ عِنْدَ اللَّهِ وَلَا أَحَبُّ إِلَيْهِ مِنْ الْعَمَلِ فِيهِنَّ مِنْ هَذِهِ الْأَيَّامِ الْعَشْرِ فَأَكْثِرُوا فِيهِنَّ مِنْ التَّهْلِيلِ وَالتَّكْبِيرِ وَالتَّحْمِيدِ
Narrated to us [Affan] Narrated to us [Abu Awanah] Narrated to us [Yazid bin Abi Ziyad] from [Mujahid] from [Ibn Umar] from the Prophet sallallaahu 'alaihi wasallam, he said: "There is no day whose reward is greater in the sight of Allah and doing good deeds on that day is more beloved in the sight of Allah than these ten days (laylalatul qadar). Therefore increase your number of bertahlil, bertakbir and bertahmid".
