[Machine] The Messenger of Allah ﷺ said, "There is no believer who dies and a group of Muslims pray upon him, reaching the number of three rows, except that he will be forgiven." Malik ibn Hubayrah used to make sure, when the family of a deceased person is few, to make them three rows.  

قَالَ رَسُولُ اللهِ ﷺ مَا مِنْ مُؤْمِنٍ يَمُوتُ فَيُصَلِّي عَلَيْهِ أُمَّةٌ مِنَ الْمُسْلِمِينَ يَبَلَغُوا أَنْ يَكُونُوا ثَلَاثَ صُفُوفٍ إِلَّا غُفِرَ لَهُ قَالَ فَكَانَ مَالِكُ بْنُ هُبَيْرَةَ يَتَحَرَّى إِذَا قَلَّ أَهْلُ جَنَازَةٍ أَنْ يَجْعَلَهُمْ ثَلَاثَ صُفُوفٍ
