Allah informs all people that a plain, unequivocal proof has come to them from Him. One that eradicates all possibility of having an excuse, or falling prey to evil doubts. Allah said,

﴿وَأَنزَلْنَآ إِلَيْكُمْ نُوراً مُّبِيناً﴾

(and We sent down to you a manifest light.) that directs to the Truth. Ibn Jurayj and others said, "It is the Qur'an.''

﴿فَأَمَّا الَّذِينَ ءَامَنُواْ بِاللَّهِ وَاعْتَصَمُواْ بِهِ﴾

(So, as for those who believed in Allah and held fast to ﴿depend on﴾ Him,) by worshipping Him and relying on Him for each and every thing. Ibn Jurayj said that this part of the Ayah means, "They believe in Allah and hold fast to the Qur'an.''

﴿فَسَيُدْخِلُهُمْ فِى رَحْمَةٍ مَّنْهُ وَفَضْلٍ﴾

(He will admit them to His mercy and grace,) meaning, He will grant them His mercy and admit them into Paradise, and will increase and multiply their rewards and their ranks, as a favor and bounty from Him.

﴿وَيَهْدِيهِمْ إِلَيْهِ صِرَطاً مُّسْتَقِيماً﴾

(and guide them to Himself by a straight path.) and a clear way that has no wickedness in it or deviation. This, indeed, is the description of the believers in this life and the Hereafter, as they are on the straight and safe path in matters of action and creed. In the Hereafter, they are on the straight path of Allah that leads to the gardens of Paradise.

﴿يَسْتَفْتُونَكَ قُلِ اللَّهُ يُفْتِيكُمْ فِى الْكَلَـلَةِ إِن امْرُؤٌ هَلَكَ لَيْسَ لَهُ وَلَدٌ وَلَهُ أُخْتٌ فَلَهَا نِصْفُ مَا تَرَكَ وَهُوَ يَرِثُهَآ إِن لَّمْ يَكُنْ لَّهَآ وَلَدٌ فَإِن كَانَتَا اثْنَتَيْنِ فَلَهُمَا الثُّلُثَانِ مِمَّا تَرَكَ وَإِن كَانُواْ إِخْوَةً رِّجَالاً وَنِسَآءً فَلِلذَّكَرِ مِثْلُ حَظِّ الاٍّنثَيَيْنِ يُبَيِّنُ اللَّهُ لَكُمْ أَن تَضِلُّواْ وَاللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌ ﴾

(176. They ask you for a legal verdict. Say: "Allah directs (thus) about Al-Kalalah. If it is a man that dies leaving a sister, but no child, she shall have half the inheritance, and ﴿in her case﴾ he will be her heir if she has no children. If there are two sisters, they shall have two-thirds of the inheritance; if there are brothers and sisters, the male will have twice the share of the female. (Thus) does Allah make clear to you (His Law) lest you go astray. And Allah is the All-Knower of everything.'')
