Does janaazah prayer in al-Haram al-Makki bring a multiple reward?
Question

                What about janaazah (funeral) prayer in al-Haram (in Makkah) – does it bring a multiple reward?.
Praise be to Allah.It is proven from the 
    Prophet  (peace and blessings of Allaah be upon him) that prayer in 
    al-Masjid al-Haraam is better than a hundred thousand prayers (offered 
    elsewhere). See Irwa’ al-Ghaleel 91129). 
The scholars differed as to 
    whether this multiple reward applies only to the five prescribed prayers or 
    does it include others as well? 
Al-Nawawi (may Allaah have 
    mercy on him) said in Sharh Muslim: It should be noted that our view 
    is that the superiority of prayer in these two mosques does not apply only 
    to the obligatory prayers, rather it includes both obligatory and naafil 
    (supererogatory) prayers. This is the view of Mutarrif among the companions 
    of Maalik. Al-Tahhaawi said: It applies only to the obligatory prayers, but 
    this is contrary to the general meaning of these saheeh ahaadeeth. And 
    Allaah knows best. End quote. 
Shaykh Ibn ‘Uthaymeen (may 
    Allaah have mercy on him) was asked: Does janaazah prayer in al-Haram 
    al-Makki bring a multiple reward like other prayers? 
He replied: There is a 
    difference of opinion among the scholars concerning this. Some scholars say 
    that what brings the multiple reward in al-Masjid al-Haraam is the five 
    daily prayers only, and other prayers do not bring the multiple reward. What 
    appears to be the case from the apparent meaning of the hadeeth is that it 
    includes all prayers, and the janaazah prayer is included in this general 
    meaning of the reward for prayers in al-Masjid al-Haraam being multiplied. 
    And Allaah knows best. End quote from Liqa’ al-baab il-Maftooh 
    (116/11).
And Allaah knows best.
