‘Abd Allaah bin ‘Amr bin Al ‘As said “The Apostle of Allaah ﷺ stopped during the Farewell Pilgrimage at Mina, as the people were to ask him(about the rites of Hajj). A man came and said Apostle of Allaah being ignorant, I shaved before sacrificing. The Apostle of Allaah ﷺ replied “Sacrifice, for no harm will come.” Another man came and said “Apostle of Allaah ﷺ, being ignorant, I sacrificed before throwing the pebbles.” He replied “Throw them for no harm will come.” He (the Prophet) was not asked about anything which had been done before or after its proper time without saying “Do it, for no harm will come.”  

أَنَّهُ قَالَ وَقَفَ رَسُولُ اللَّهِ ﷺ فِي حَجَّةِ الْوَدَاعِ بِمِنًى يَسْأَلُونَهُ فَجَاءَهُ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي لَمْ أَشْعُرْ فَحَلَقْتُ قَبْلَ أَنْ أَذْبَحَ فَقَالَ رَسُولُ اللَّهِ ﷺ اذْبَحْ وَلاَ حَرَجَ وَجَاءَ رَجُلٌ آخَرُ فَقَالَ يَا رَسُولَ اللَّهِ لَمْ أَشْعُرْ فَنَحَرْتُ قَبْلَ أَنْ أَرْمِيَ قَالَ ارْمِ وَلاَ حَرَجَ قَالَ فَمَا سُئِلَ يَوْمَئِذٍ عَنْ شَىْءٍ قُدِّمَ أَوْ أُخِّرَ إِلاَّ قَالَ اصْنَعْ وَلاَ حَرَجَ  

Usamah bin Sharik said “I went out with the Prophet ﷺ to perform Hajj, and the people were coming to him. One would say “Apostle of Allaah ﷺ I ran between Al Safa’ and Al Marwah before going round the Ka’bah or I did something before the its proper time or did something after its proper time. He would reply “No harm will come; no harm will come except to one who defames a Muslim acting wrongfully. That is the one who will be in trouble and will perish.  

خَرَجْتُ مَعَ النَّبِيِّ ﷺ حَاجًّا فَكَانَ النَّاسُ يَأْتُونَهُ فَمَنْ قَالَ يَا رَسُولَ اللَّهِ سَعَيْتُ قَبْلَ أَنْ أَطُوفَ أَوْ قَدَّمْتُ شَيْئًا أَوْ أَخَّرْتُ شَيْئًا فَكَانَ يَقُولُ لاَ حَرَجَ لاَ حَرَجَ إِلاَّ عَلَى رَجُلٍ اقْتَرَضَ عِرْضَ رَجُلٍ مُسْلِمٍ وَهُوَ ظَالِمٌ فَذَلِكَ الَّذِي حَرِجَ وَهَلَكَ
