Ibn Abi Mulaykah (may Allah have mercy on him) narrates: I wrote to Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) and asked about the testimony of children. So he wrote back to me: "Allah, the Mighty and Majestic, says: ﴿mimman tardawna min ash-shuhada’﴾ meaning, 'from among those whose testimony you are pleased with.' Children are not among those whose testimony we consider reliable, therefore their testimony is not permissible."

Mujahid (may Allah have mercy on him) regarding this verse: "And call to witness two witnesses from among your men" says: "By this is meant free men."

Mujahid (may Allah have mercy on him) was asked: If a person pronounces zihar on his slave woman, what is the ruling? He replied: "This zihar is nothing." It was asked: "Did Allah Almighty not say: ﴿وَالَّذِينَ يُظَاهِرُونَ مِنْ نِسَائِهِمْ﴾ 'And those who pronounce zihar from their wives,' so are slave women not included among women?" Upon this, Mujahid (may Allah have mercy on him) said: "Allah Almighty also said: ﴿وَاسْتَشْهِدُوا شَهِيدَيْنِ مِنْ رِجَالِكُمْ﴾ 'And take two male witnesses from among your men,' so is the testimony of slaves permissible?" That is, just as in the matter of testimony, the condition of men is specified and slaves are not included, similarly in the ruling of 'wives,' free women are meant, not slave women.
