Shaykh of rafidah Muhammad Baqir al-Majlisi reported in his book “Malathil akhyar” (1/376-377, thk Sayyyed Mahdi ar-Raji) from Imam Abu Abdullah (alaihi salam), that he was teaching his companions proper way of ablution, and he said:
وَ إِنْ نَسِيتَ مَسْحَ رَأْسِكَ حَتَّى تَغْسِلَ رِجْلَيْكَ فَامْسَحْ رَأْسَكَ ثُمَّ اغْسِلْ رِجْلَيْك
If (during the minor ablution) you forgot to wipe your head till you have (already) WASHED YOUR LEGS, then in this case, wipe your head, and then WASH YOUR LEGS.
Grading of hadith by al-Majlisi: Al-Muwathaq. (Reliable)
This rafidi shaykh reported other hadith regarding washing the feet. (“Malathil akhyar” 1/284):
عَنْ أَيُّوبَ بْنِ نُوحٍ قَالَ كَتَبْتُ إِلَى أَبِي الْحَسَنِ ع أَسْأَلُهُ عَنِ الْمَسْحِ عَلَى الْقَدَمَيْنِ فَقَالَ الْوُضُوءُ بِالْمَسْحِ وَ لَا يَجِبُ فِيهِ إِلَّا ذَلِكَ وَ مَنْ غَسَلَ فَلَا بَأْس
From Ayub ibn Nooh: I wrote to Abul hasan (alaihi salam), and asked him about wiping the feet, he said: Ablution by wiping, and there is nothing obligatory apart from this, BUT IF SOMEONE WASHED (THEIR FEET) NO PROBLEM WITH THAT.
Grading of hadith from Majlisi: Saheeh.
This hadith was also transimitted by other shia shaykh – al-Bahrani in his “Hadaiq an-nadira” (2/290), and he also said hadith is saheeh:
