´It was narrated that ‘Aishah said:` “If the Messenger of Allah (ﷺ) missed the four Rak’ah before the Zuhr, he would perform them after the two Rak’ah which come after the Zuhr.”

Hadith Takhrij« سنن الترمذی/الصلاة 201 ( 426 ) ، ( تحفة الأشراف : 16208 ) ( ضعیف ) » ( اس باب میں صحیح حدیث کریب کی ہے ، جو ام سلمہ اور عائشہ رضی اللہ عنہما سے مروی ہے ، ملاحظہ ہو : سلسلة الاحادیث الضعیفة ، للالبانی : 4208 )
´Aishah narrated:` "When the Prophet (S) would not perform the four Rak'ah before Az-Zuhr he would pray them after it."
Shaykh Dr. Abdur Rahman Freywai
1؎ : From this, it is evident that the Prophet (sallallahu alayhi wa sallam) was diligent in observing these Sunnahs. Therefore, we too should be diligent in performing these Sunnahs. If we are unable to perform them beforehand, then we should perform them after the obligatory (fard) prayer. However, this is not a make-up (qada) of an obligatory act.
