"The Messenger of Allah said: 'Adhere to righteousness even though you will not be able to do all acts of virtue. Know that the best of your deeds is Salat (prayer) and that no one maintains his ablution except a believer.'" (Using translation from Ibn Mājah 277)
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «اسْتَقِيمُوا وَلَنْ تُحْصُوا وَاعْلَمُوا أَنَّ مِنْ خَيْرِ أَعْمَالِكُمُ الصَّلَاةَ وَلَنْ يُحَافِظَ عَلَى الْوُضُوءِ إِلَّا مُؤْمِنٌ»
