[Machine] You were in a state of ritual impurity, so it was not permissible for you to pray. After you performed ablution (ritual washing), prayer became permissible for you, and fasting also became valid so you may observe it.
«كُنْتَ جُنُبًا لَا يَحِلُّ لَكَ الصَّلَاةُ فَاغْتَسَلْتَ فَحَلَّتْ لَكَ الصَّلَاةُ وَحَلَّ لَكَ الصِّيَامُ فَصُمْ»
[Machine] O Abu Abdurrahman, indeed I was in a state of major impurity (janabah) and did not perform the ritual purification (ghusl) until morning came. So Abdullah said, "You were in a state of major impurity, so the prayer was not permissible for you. But since you have performed the ritual purification, the prayer is permissible for you and fasting is also permissible for you." And that was during Ramadan.
يَا أَبَا عَبْدِ الرَّحْمَنِ إِنِّي كُنْتُ جُنُبًا فَلَمِ اغْتَسَلْ حَتَّى أَصْبَحْتُ فَقَالَ عَبْدُ اللهِ «كُنْتَ جُنُبًا لَا تَحِلُّ لَكَ الصَّلَاةُ فَاغْتَسَلْتَ فَحَلَّتْ لَكَ الصَّلَاةُ وَحَلَّ لَكَ الصِّيَامُ» وَذَلِكَ فِي رَمَضَانَ
