Narrated Ibrahim:
The companions of 'Abdullah (bin Mas'ud) came to Abu Darda', (and before they arrived at his home), he looked for them and found them. Then he asked them,: 'Who among you can recite (Qur'an) as 'Abdullah recites it?" They replied, "All of us." He asked, "Who among you knows it by heart?" They pointed at 'Alqama. Then he asked Alqama. "How did you hear 'Abdullah bin Mas'ud reciting Surat Al-Lail (The Night)?" Alqama recited:
'By the male and the female.' Abu Ad-Darda said, "I testify that I heard me Prophet reciting it likewise, but these people want me to recite it:--
'And by Him Who created male and female.' but by Allah, I will not follow them."
