وَمَن يَقْتُلْ مُؤْمِنًا مُّتَعَمِّدًا فَجَزَآؤُهُۥ جَهَنَّمُ خَـٰلِدًا فِيهَا وَغَضِبَ ٱللَّهُ عَلَيْهِ وَلَعَنَهُۥ وَأَعَدَّ لَهُۥ عَذَابًا عَظِيمًا

But whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment.

يَسْتَخْفُونَ مِنَ ٱلنَّاسِ وَلَا يَسْتَخْفُونَ مِنَ ٱللَّهِ وَهُوَ مَعَهُمْ إِذْ يُبَيِّتُونَ مَا لَا يَرْضَىٰ مِنَ ٱلْقَوْلِ ۚ وَكَانَ ٱللَّهُ بِمَا يَعْمَلُونَ مُحِيطًا

They conceal [their evil intentions and deeds] from the people, but they cannot conceal [them] from Allah, and He is with them [in His knowledge] when they spend the night in such as He does not accept of speech. And ever is Allah, of what they do, encompassing.

رَّبُّكُمْ أَعْلَمُ بِمَا فِى نُفُوسِكُمْ ۚ إِن تَكُونُوا۟ صَـٰلِحِينَ فَإِنَّهُۥ كَانَ لِلْأَوَّٰبِينَ غَفُورًا

Your Lord is most knowing of what is within yourselves. If you should be righteous [in intention] - then indeed He is ever, to the often returning [to Him], Forgiving.

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَقْتُلُوا۟ ٱلصَّيْدَ وَأَنتُمْ حُرُمٌ ۚ وَمَن قَتَلَهُۥ مِنكُم مُّتَعَمِّدًا فَجَزَآءٌ مِّثْلُ مَا قَتَلَ مِنَ ٱلنَّعَمِ يَحْكُمُ بِهِۦ ذَوَا عَدْلٍ مِّنكُمْ هَدْيًۢا بَـٰلِغَ ٱلْكَعْبَةِ أَوْ كَفَّـٰرَةٌ طَعَامُ مَسَـٰكِينَ أَوْ عَدْلُ ذَٰلِكَ صِيَامًا لِّيَذُوقَ وَبَالَ أَمْرِهِۦ ۗ عَفَا ٱللَّهُ عَمَّا سَلَفَ ۚ وَمَنْ عَادَ فَيَنتَقِمُ ٱللَّهُ مِنْهُ ۗ وَٱللَّهُ عَزِيزٌ ذُو ٱنتِقَامٍ

O you who have believed, do not kill game while you are in the state of ihram. And whoever of you kills it intentionally - the penalty is an equivalent from sacrificial animals to what he killed, as judged by two just men among you as an offering [to Allah] delivered to the Ka'bah, or an expiation: the feeding of needy people or the equivalent of that in fasting, that he may taste the consequence of his deed. Allah has pardoned what is past; but whoever returns [to violation], then Allah will take retribution from him. And Allah is Exalted in Might and Owner of Retribution.

Narrated `Aisha:We set out with the Prophet (ﷺ) with the intention of performing Hajj only. The Prophet (ﷺ) reached Mecca and performed Tawaf of the Ka`ba and between Safa and Marwa and did not finish the Ihram, because he had the Hadi with him. His companions and his wives performed Tawaf (of the Ka`ba and between Safa and Marwa), and those who had no Hadi with them finished their Ihram.
