وَلَا تَكُونُوا۟ كَٱلَّتِى نَقَضَتْ غَزْلَهَا مِنۢ بَعْدِ قُوَّةٍ أَنكَٰثًۭا تَتَّخِذُونَ أَيْمَٰنَكُمْ دَخَلًۢا بَيْنَكُمْ أَن تَكُونَ أُمَّةٌ هِىَ أَرْبَىٰ مِنْ أُمَّةٍ ۚ إِنَّمَا يَبْلُوكُمُ ٱللَّهُ بِهِۦ ۚ وَلَيُبَيِّنَنَّ لَكُمْ يَوْمَ ٱلْقِيَٰمَةِ مَا كُنتُمْ فِيهِ تَخْتَلِفُونَ
And be not like unto her who unravelleth the thread, after she hath made it strong, to thin filaments, making your oaths a deceit between you because of a nation being more numerous than (another) nation. Allah only trieth you thereby, and He verily will explain to you on the Day of Resurrection that wherein ye differed.
Surah An-Nahl(16:92)
Sahih al-Bukhari
Shortening the Prayers (At-Taqseer)
Chapter: Whoever starts his Salat sitting (because of ailment) and then during the Salat (prayer) feels better, can finish the rest while standing
Narrated Aisha:
(the mother of the faithful believers) I never saw Allah's Messenger (ﷺ) offering the night prayer while sitting except in his old age and then he used to recite while sitting and whenever he wanted to bow he would get up and recite thirty or forty verses (while standing) and then bow.
Sahih al-Bukhari 1118
