that the Messenger of Allah became angry with Safiyyah bint Huyai for something, and Safiyyah said: "O 'Aishah, can you make the Messenger of Allah be pleased with me, and I will give you my day?" She said: "Yes." So she took a headcover of hers that was dyed with saffron and sprinkled it with water so that its fragrance would become stronger, then she sat beside the Messenger of Allah. The Prophet said: "O 'Aishah, go away, because it is not your day!" She said: "That is the Grace of Allah which He bestows on whom He pleases." Then she told him about that matter and he was pleased with her. (Using translation from Ibn Mājah 1973)
أَنَّ رَسُولَ اللهِ ﷺ وَجَدَ عَلَى صَفِيَّةَ بِنْتَ حُيَيٍّ فِي شَيْءٍ فَقَالَتْ صَفِيَّةُ يَا عَائِشَةُ أَرْضِي عَنِّي رَسُولَ اللهِ ﷺ وَلَكِ يَوْمِي فَقَالَتْ نَعَمْ فَأَخَذَتْ خِمَارًا لَهَا مَصْبُوغًا بِزَعْفَرَانٍ فَرَشَّتْهُ بِالْمَاءِ لِيَفُوحَ رِيحُهُ فَقَعَدَتْ إِلَى جَنْبِ رَسُولِ اللهِ ﷺ فَقَالَ رَسُولُ اللهِ ﷺ إِلَيْكِ يَا عَائِشَةُ إِنَّهُ لَيْسَ يَوْمَكِ قَالَتْ ذَلِكَ فَضْلُ اللهِ يُؤْتِيهِ مَنْ يَشَاءُ وَأَخْبَرَتْهُ بِالْأَمْرِ فَرَضِيَ عَنْهَا
