I intended to prohibit cohabitation with a suckling woman until I considered that the Romans and the Persians do it without any injury being caused to their children thereby. (Imam Muslim said: Khalaf reported it from Judamat al-'Asadiyya, but the correct wording is what has been stated by Yahya.)  

أَنَّهَا سَمِعَتْ رَسُولَ اللَّهِ ﷺ يَقُولُ لَقَدْ هَمَمْتُ أَنْ أَنْهَى عَنِ الْغِيلَةِ حَتَّى ذَكَرْتُ أَنَّ الرُّومَ وَفَارِسَ يَصْنَعُونَ ذَلِكَ فَلاَ يَضُرُّ أَوْلاَدَهُمْ قَالَ مُسْلِمٌ وَأَمَّا خَلَفٌ فَقَالَ عَنْ جُذَامَةَ الأَسَدِيَّةِ وَالصَّحِيحُ مَا قَالَهُ يَحْيَى بِالدَّالِ  

I intended to prohibit suckling during pregnancy (ghailah), but I considered the Greeks and the Persians and saw that they practiced it, without any injury being caused to their children thereby. Malik said : Ghailah means that a man has intercourse with a women while she is suckling a child.  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ عَنْ جُدَامَةَ الأَسَدِيَّةِ أَنَّهَا سَمِعَتْ رَسُولَ اللَّهِ ﷺ يَقُولُ لَقَدْ هَمَمْتُ أَنْ أَنْهَى عَنِ الْغَيْلَةِ حَتَّى ذُكِّرْتُ أَنَّ الرُّومَ وَفَارِسَ يَفْعَلُونَ ذَلِكَ فَلاَ يَضُرُّ أَوْلاَدَهُمْ قَالَ مَالِكٌ الْغَيْلَةُ أَنْ يَمَسَّ الرَّجُلُ امْرَأَتَهُ وَهِيَ تُرْضِعُ  

Yahya related to me from Malik that Muhammad ibn Abd ar-Rahman ibn Nawfal said, ''Urwa ibn az-Zubayr informed me from A'isha umm al- muminin that Judama bint Wahb al-Asadiyya informed her that she heard the Messenger of Allah ﷺ say, 'I intended to prohibit ghila but I remembered that the Greeks and Persians do that without it causing any injury to their children.' " Malik explained, "Ghila is that a man has intercourse with his wife while she is suckling."  

أَنَّهَا سَمِعَتْ رَسُولَ اللَّهِ ﷺ يَقُولُ لَقَدْ هَمَمْتُ أَنْ أَنْهَى عَنِ الْغِيلَةِ حَتَّى ذَكَرْتُ أَنَّ الرُّومَ وَفَارِسَ يَصْنَعُونَ ذَلِكَ فَلاَ يَضُرُّ أَوْلاَدَهُمْ  

[Machine] The Messenger of Allah ﷺ said, "I had intended to forbid the practice of Ghila (maternal aunt) but then I remembered that the Persians and the Romans practice it and it does not harm their children." Abu Muhammad said, "Ghila refers to sexual intercourse with a woman while she is breastfeeding."  

قَالَ رَسُولُ اللَّهِ ﷺ «لَقَدْ هَمَمْتُ أَنْ أَنْهَى عَنِ الْغِيلَةِ حَتَّى ذَكَرْتُ أَنَّ فَارِسَ وَالرُّومَ يَصْنَعُونَ ذَلِكَ فَلَا يَضُرُّ أَوْلَادَهُمْ» قَالَ أَبُو مُحَمَّد «الْغِيلَةُ أَنْ يُجَامِعَهَا وَهِيَ تُرْضِعُ»  

I intended to prohibit suckling during pregnancy (ghailah), but I considered the Greeks and the Persians and saw that they practiced it, without any injury being caused to their children thereby. Malik said : Ghailah means that a man has intercourse with a women while she is suckling a child. (Using translation from Abū Dāʾūd 3882)   

أَنَّهَا سَمِعَتْ رَسُولَ اللَّهِ ﷺ يَقُولُ «لَقَدْ هَمَمْتُ أَنْ أَنْهَى عَنِ الْغِيلَةِ حَتَّى ذَكَرْتُ أَنَّ الرُّومَ وَفَارِسَ يَصْنَعُونَ ذَلِكَ فَلَا يَضُرُّ أَوْلَادَهُمْ» قَالَ مَالِكٌ وَالْغِيلَةُ أَنْ يَمَسَّ الرَّجُلُ امْرَأَتَهُ وَهِيَ تُرْضِعُ
