Hadith 10:274
Abu Ayyub told of hearing God’s Messenger say, “If anyone separates a mother from her child, God will separate him from his friends on the day of resurrection.” Tirmidhi and Darimi transmitted it.
وَعَن أبي أيوبَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ فَرَّقَ بَيْنَ وَالِدَةٍ وَوَلَدِهَا فَرَّقَ اللَّهُ بَيْنَهُ وَبَيْنَ أَحِبَّتِهِ يَوْمَ الْقِيَامَةِ» . رَوَاهُ التِّرْمِذِيّ والدارمي
