1 عَنْ سُلَیْمَانَ بْنِ حَفْصٍ الْمَرْوَزِیِّ قَالَ: قَالَ أَبُو الْحَسَنِ الْأَخِیرُ إِیَّاکَ وَ النَّوْمَ بَیْنَ صَلَاةِ اللَّیْلِ وَ الْفَجْرِ وَ لَکِنْ ضَجْعَةً بِلَا نَوْمٍ فَإِنَّ صَاحِبَهُ لَا یُحْمَدُ عَلَی مَا قَدَّمَ مِنْ صَلَاتِهِ.
📚 Al-Tahdhib, Vol. 2, p. 137
Imam Abu al-Hasan (peace be upon him) said: Avoid sleeping between the Night Prayer and the Morning Prayer; however, lie down on your side without sleeping, for (in the case of sleeping), a person is not praised for the prayers he has previously performed!
2 عَنْ إِبْرَاهِیمَ بْنِ أَبِی الْبِلَادِ قَالَ: صَلَّیْتُ خَلْفَ الرِّضَا فِی الْمَسْجِدِ الْحَرَامِ صَلَاةَ اللَّیْلِ فَلَمَّا فَرَغَ جَعَلَ مَکَانَ الضَّجْعَةِ سَجْدَةً.
📚 Al-Kafi, Vol. 3, p. 448
Ibrahim ibn Abi al-Bilad said: I performed the Night Prayer in Masjid al-Haram behind Imam al-Rida (peace be upon him); when he finished, instead of lying on his side, he performed a prostration (Sajdah)!
3 عَنْ إِبْرَاهِیمَ بْنِ أَبِی الْبِلَادِ قَالَ: صَلَّی أَبُو الْحَسَنِ الْأَوَّلُ صَلَاةَ اللَّیْلِ فِی الْمَسْجِدِ الْحَرَامِ وَ أَنَا خَلْفَهُ فَصَلَّی الثَّمَانَ وَ أَوْتَرَ وَ صَلَّی الرَّکْعَتَیْنِ ثُمَّ جَعَلَ مَکَانَ الضَّجْعَةِ سَجْدَةً.
📚 Qurb al-Isnad, 128
Ibrahim ibn Abi al-Bilad said: Imam al-Kazim (peace be upon him) performed his Night Prayer in Masjid al-Haram while I was behind him. He performed eight rak'ahs (of the Night Prayer), then performed his Witr prayer, then performed the two rak'ahs (of the Morning Nafl), and instead of the Daj'ah (i.e., lying on the side without sleep between the Night Prayer and the Morning Prayer), he performed a prostration!
4 عَنِ الْحُسَیْنِ بْنِ عُثْمَانَ عَنْ رَجُلٍ عَنْ أَبِی عَبْدِ اللَّهِ قَالَ: یُجْزِیکَ مِنَ الِاضْطِجَاعِ بَعْدَ رَکْعَتَیِ الْفَجْرِ الْقِیَامُ وَ الْقُعُودُ وَ الْکَلَامُ بَعْدَ رَکْعَتَیِ الْفَجْرِ.
📚 Al-Tahdhib, Vol. 2, p. 137
Imam al-Sadiq (peace be upon him) said: Instead of lying on your side after the Morning Nafl, standing, sitting, or speaking after the Morning Nafl suffices for you!
5 عَنْ زُرَارَةَ عَنْ أَبِی جَعْفَرٍ قَالَ: إِنَّمَا عَلَی أَحَدِکُمْ إِذَا انْتَصَفَ اللَّیْلُ أَنْ یَقُومَ فَیُصَلِّیَ صَلَاتَهُ جُمْلَةً وَاحِدَةً ثَلَاثَ عَشْرَةَ رَکْعَةً ثُمَّ إِنْ شَاءَ جَلَسَ فَدَعَا وَ إِنْ شَاءَ نَامَ وَ إِنْ شَاءَ ذَهَبَ حَیْثُ شَاءَ.
📚 Al-Tahdhib, Vol. 2, p. 137
Imam al-Baqir (peace be upon him) said: It is indeed incumbent upon each of you that when the night reaches its middle, he should perform thirteen rak'ahs (of the Night Nafl) all at once; then if he wishes, he may sit and supplicate, and if he wishes, he may sleep, and if he wishes, he may go wherever he desires!
6 عَنْ عُمَرَ بْنِ یَزِیدَ قَالَ: قَالَ أَبُو عَبْدِ اللَّهِ إِنْ خِفْتَ الشُّهْرَةَ فِی التُّکَأَةِ فَقَدْ یُجْزِیکَ أَنْ تَضَعَ یَدَکَ عَلَی الْأَرْضِ وَ لَا تَضْطَجِعْ وَ أَوْمَأَ بِأَطْرَافِ أَصَابِعِهِ مِنْ کَفِّهِ الْیُمْنَی فَوَضَعَهَا فِی الْأَرْضِ قَلِیلًا وَ حَکَی أَبُو جَعْفَرٍ ذَلِکَ.

Imam al-Sadiq (peace be upon him) said: If you fear becoming famous (showing off) regarding leaning (i.e., lying on the side without sleep between the Night Prayer and the Morning Prayer), it is sufficient to place your hand on the ground and not lie on your side. The Imam gestured with the fingertips of his right hand and placed them slightly on the ground (to demonstrate the method), and Imam al-Baqir (peace be upon him) narrated the same!
7 عَنْ عَلِیِّ بْنِ جَعْفَرٍ عَنْ أَخِیهِ مُوسَی بْنِ جَعْفَرٍ قَالَ: سَأَلْتُهُ عَنْ رَجُلٍ نَسِیَ أَنْ یَضْطَجِعَ عَلَی یَمِینِهِ بَعْدَ رَکْعَتَیِ الْفَجْرِ فَذَکَرَ حِینَ أَخَذَ فِی الْإِقَامَةِ کَیْفَ یَصْنَعُ قَالَ یُقِیمُ وَ یُصَلِّی وَ یَدَعُ ذَلِکَ فَلَا بَأْسَ.
📚 Al-Tahdhib, Vol. 2, p. 338
Ali ibn Ja'far said: I asked Imam al-Kazim (peace be upon him) about a person who forgets to lie on his right side after the Morning Nafl and remembers just as he begins the Iqamah for the Morning prayer—what should he do? The Imam said: 'He says the Iqamah and performs the prayer; he leaves it (the Daj'ah) and there is no problem!'
