It is recommended to stay overnight in Dhu Tuwa when intending to enter Makkah, and to perform Ghusl before entering it, and to enter it by day

Ibn Umar (Allah be pleased with him) reported that Allah's Messenger (ﷺ) ﷺ) spent the night at Dhi Tuwa till it was dawn and then entered Mecca. 'Abdullah (b. 'Umar) himself did like it. And in the narration transmitted by Ibn Sa'ld (the words are):

Until he obrerved the dawn prayer. Yahya (another narrator) said: Until it was dawn.

حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، وَعُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا يَحْيَى، - وَهُوَ الْقَطَّانُ - عَنْ عُبَيْدِ اللَّهِ، أَخْبَرَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم بَاتَ بِذِي طَوًى حَتَّى أَصْبَحَ ثُمَّ دَخَلَ مَكَّةَ ‏.‏ قَالَ وَكَانَ عَبْدُ اللَّهِ يَفْعَلُ ذَلِكَ ‏.‏ وَفِي رِوَايَةِ ابْنِ سَعِيدٍ حَتَّى صَلَّى الصُّبْحَ ‏.‏ قَالَ يَحْيَى أَوْ قَالَ حَتَّى أَصْبَحَ ‏.‏

Nafi' reported that Ibn Umar (Allah be pleased with them) did not enter Mecca without spending the night at Dhi Tawu until it was dawn, when he took a bath, and then entered Mecca in the morning, and made a mention that Allah's Messenger (ﷺ) did that.

وَحَدَّثَنَا أَبُو الرَّبِيعِ الزَّهْرَانِيُّ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا أَيُّوبُ، عَنْ نَافِعٍ، أَنَّ ابْنَ عُمَرَ، كَانَ لاَ يَقْدَمُ مَكَّةَ إِلاَّ بَاتَ بِذِي طَوًى حَتَّى يُصْبِحَ وَيَغْتَسِلَ ثُمَّ يَدْخُلُ مَكَّةَ نَهَارًا وَيَذْكُرُ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ فَعَلَهُ ‏.‏

Abdullah (b. 'Umar) reported that whenever Allah's Messenger (ﷺ) entered Mecca, he got down at Dhi Tuwa and spend the night there until he observed the dawn prayer. And Allah's Messenger (ﷺ) observed this prayer on a rough hillock, and not in the mosque which had been then built there, but to the lower side of it (the mosque) on a hillock.

وَحَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ الْمُسَيَّبِيُّ، حَدَّثَنِي أَنَسٌ، - يَعْنِي ابْنَ عِيَاضٍ - عَنْ مُوسَى بْنِ عُقْبَةَ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ، حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَنْزِلُ بِذِي طَوًى وَيَبِيتُ بِهِ حَتَّى يُصَلِّيَ الصُّبْحَ حِينَ يَقْدَمُ مَكَّةَ وَمُصَلَّى رَسُولِ اللَّهِ صلى الله عليه وسلم ذَلِكَ عَلَى أَكَمَةٍ غَلِيظَةٍ لَيْسَ فِي الْمَسْجِدِ الَّذِي بُنِيَ ثَمَّ وَلَكِنْ أَسْفَلَ مِنْ ذَلِكَ عَلَى أَكَمَةٍ غَلِيظَةٍ ‏.‏

Nafi' reported that Abdullah (b. 'Umar) informed him that Allah's Messenger (ﷺ) turned his face to the two hillocks which intervened between him and the long mountain by the side of the Ka'ba, and the mosque which had been built there was thus on the left of the hillock. Allah's Messenger (ﷺ) 's (ﷺ) place of prayer was lower than the black hillock, at a distance of ten cubits or near it. He (ﷺ) would then observe prayer facing these two hillocks of the long mountain that is intervening between you and the Ka'ba.

حَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ الْمُسَيَّبِيُّ، حَدَّثَنِي أَنَسٌ، - يَعْنِي ابْنَ عِيَاضٍ - عَنْ مُوسَى، بْنِ عُقْبَةَ عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ، أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم اسْتَقْبَلَ فُرْضَتَىِ الْجَبَلِ الَّذِي بَيْنَهُ وَبَيْنَ الْجَبَلِ الطَّوِيلِ نَحْوَ الْكَعْبَةِ يَجْعَلُ الْمَسْجِدَ الَّذِي بُنِيَ ثَمَّ يَسَارَ الْمَسْجِدِ الَّذِي بِطَرَفِ الأَكَمَةِ وَمُصَلَّى رَسُولِ اللَّهِ صلى الله عليه وسلم أَسْفَلَ مِنْهُ عَلَى الأَكَمَةِ السَّوْدَاءِ يَدَعُ مِنَ الأَكَمَةِ عَشْرَ أَذْرُعٍ أَوْ نَحْوَهَا ثُمَّ يُصَلِّي مُسْتَقْبِلَ الْفُرْضَتَيْنِ مِنَ الْجَبَلِ الطَّوِيلِ الَّذِي بَيْنَكَ وَبَيْنَ الْكَعْبَةِ صلى الله عليه وسلم ‏.‏
