Khalid’s ibn Ma’dan statement regarding spending five nights of the year in ‘ibadah

Question:

I want to know the authenticity of this particular saying of Tabi’i Khalid ibn Ma’dan (rahimahullah) who said:

“There are five particular nights in a whole year, whosoever spends these nights in worship with intention of gaining virtues and believing [in its promised virtues], Allah will grant him entrance into Jannah

1. The first night of Rajab (worships in the night and fasts during the day for all)

2) The 15th night of Sha’ban

3 and 4) Both nights of ‘Eid (fasting the day preceding these nights or some versions state ‘Does not fast the next day’)

5. The night of ‘Ashura.’
