قُلْ إِن كَانَ آبَاؤُكُمْ وَأَبْنَآؤُكُمْ وَإِخْوَانُكُمْ وَأَزْوَاجُكُمْ وَعَشِيرَتُكُمْ وَأَمْوَالٌ اقْتَرَفْتُمُوهَا وَتِجَارَةٌ تَخْشَوْنَ كَسَادَهَا وَمَسَاكِنُ تَرْضَوْنَهَا أَحَبَّ إِلَيْكُم مِّنَ اللّهِ وَرَسُولِهِ وَجِهَادٍ فِي سَبِيلِهِ فَتَرَبَّصُواْ حَتَّى يَأْتِيَ اللّهُ بِأَمْرِهِ وَاللّهُ لاَ يَهْدِي الْقَوْمَ الْفَاسِقِينَ
Allah says, "Say: 'If it be that your fathers, your sons, your brothers, your mates, or your kindred; the wealth that ye have gained; the commerce in which ye fear a decline: or the dwellings in which ye delight - are dearer to you than Allah, or His Messenger, or the striving in His cause;- then wait until Allah brings about His decision: and Allah guides not the rebellious." (9:24)
Hadith #3
Narated By 'Abdullah bin Hisham : We were with the Prophet and he was holding the hand of 'Umar bin Al-Khattab. 'Umar said to Him, "O Allah's Apostle! You are dearer to me than everything except my own self." The Prophet said, "No, by Him in Whose Hand my soul is, (you will not have complete faith) till I am dearer to you than your own self." Then 'Umar said to him, "However, now, by Allah, you are dearer to me than my own self." The Prophet said, "Now, O 'Umar, (now you are a believer)."
