semen

Washing visible and non-visible impurities

Q: I had a question regarding the purity or purification of bed sheets or similar stuff impacted with semen (both visible stains as well as invisible). Please give a detailed and clear idea about the ruling regarding the same. If it is impure then how do I wash large bed sheets, mattresses or blankets in both cases having visible semen stains as well as non visible semen. If I sleep in the same setup do my cloths or body get impure?

Semen coming out after ghusal

Q: I woke up after having a wet dream. I immediately made Ghusl and then remained awake for sometime during which I performed Salaat. I then urinated. A sticky, semen-like fluid came out with the urine. The urine was also very cloudy indicting the possible presence of semen therein. I therefore made Ghusl again.

1. Was it necessary for me to make Ghusl again after observing this about the urine?

2. Was the Salaat valid?

Impurity on the bed

Q: If a towel was put on the bed and some semen after intercourse went on it which then transferred to the other bottom side of the towel which was touching the bed sheet then does that mean the bed sheet is also impure? This is because the wetness of the semen from the bottom side of the towel touching the bedsheets could've been transferred. Although when checked after few minutes the sheet was dry and and there were no stains. Should I have to wash the bed sheet?
