I heard Jabir bin ʿAbdullah in a gathering saying, "We, the companions of Messenger of Allah ﷺ assumed the state of Ihram to perform only Hajj without ʿUmra." Jabir added, "The Prophet ﷺ arrived (at Mecca) on the fourth of Dhul-Hijja. And when we arrived (in Mecca) the Prophet ﷺ ordered us to finish the state of Ihram, saying, "Finish your lhram and go to your wives (for sexual relation)." Jabir added, "The Prophet did not oblige us (to go to our wives) but he only made that legal for us. Then he heard that we were saying, "When there remains only five days between us and the Day of ʿArafat he orders us to finish our Ihram by sleeping with our wives in which case we will proceed to ʿArafat with our male organs dribbling with semen?' (Jabir pointed out with his hand illustrating what he was saying). Messenger of Allah ﷺ stood up and said, 'You (People) know that I am the most Allah-fearing, the most truthful and the best doer of good deeds (pious) from among you. If I had not brought the Hadi with me, I would have finished my Ihram as you will do, so finish your Ihram. If I had formerly known what I came to know lately, I would not have brought the Hadi with me.' So we finished our Ihram and listened to the Prophet ﷺ and obeyed him." (See Hadith No. 713, Vol. 2)  

أَهْلَلْنَا أَصْحَابَ رَسُولِ اللَّهِ ﷺ فِي الْحَجِّ خَالِصًا لَيْسَ مَعَهُ عُمْرَةٌ قَالَ عَطَاءٌ قَالَ جَابِرٌ فَقَدِمَ النَّبِيُّ ﷺ صُبْحَ رَابِعَةٍ مَضَتْ مِنْ ذِي الْحِجَّةِ فَلَمَّا قَدِمْنَا أَمَرَنَا النَّبِيُّ ﷺ أَنْ نَحِلَّ وَقَالَ أَحِلُّوا وَأَصِيبُوا مِنَ النِّسَاءِ قَالَ عَطَاءٌ قَالَ جَابِرٌ وَلَمْ يَعْزِمْ عَلَيْهِمْ وَلَكِنْ أَحَلَّهُنَّ لَهُمْ فَبَلَغَهُ أَنَّا نَقُولُ لَمَّا لَمْ يَكُنْ بَيْنَنَا وَبَيْنَ عَرَفَةَ إِلاَّ خَمْسٌ أَمَرَنَا أَنْ نَحِلَّ إِلَى نِسَائِنَا فَنَأْتِي عَرَفَةَ تَقْطُرُ مَذَاكِيرُنَا الْمَذْىَ قَالَ وَيَقُولُ جَابِرٌ بِيَدِهِ هَكَذَا وَحَرَّكَهَا فَقَامَ رَسُولُ اللَّهِ ﷺ فَقَالَ قَدْ عَلِمْتُمْ أَنِّي أَتْقَاكُمْ لِلَّهِ وَأَصْدَقُكُمْ وَأَبَرُّكُمْ وَلَوْلاَ هَدْيِي لَحَلَلْتُ كَمَا تَحِلُّونَ فَحِلُّوا فَلَوِ اسْتَقْبَلْتُ مِنْ أَمْرِي مَا اسْتَدْبَرْتُ مَا أَهْدَيْتُ فَحَلَلْنَا وَسَمِعْنَا وَأَطَعْنَا  

The Prophet ﷺ said, "Perform (an optional) prayer before Maghrib prayer." (He repeated it thrice) and the third time he said, "Whoever wants to offer it can do so," lest the people should take it as a Sunna (tradition). (See Hadith No. 277, Vol. 2)  

عَنِ النَّبِيِّ ﷺ قَالَ صَلُّوا قَبْلَ صَلاَةِ الْمَغْرِبِ قَالَ فِي الثَّالِثَةِ لِمَنْ شَاءَ كَرَاهِيَةَ أَنْ يَتَّخِذَهَا النَّاسُ سُنَّةً
